Ohm's law states that the electrical current (i) flowing in an circuit is proportional to the voltage (v) and inversely proportional to the resistance (r)therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change. Best answer: well according to ohms law i=e/r the current flowing through a circuit equals to the voltage divided by the resistance so i can only think of 2 factors voltage and resistance. A current that brings warmth into a high latitude region will make that region's climate less chilly surface ocean currents can create eddies, swirling loops of water, as they flow surface ocean currents can also affect upwelling in many places. Ohm's law (again) there must be voltage available to motivate electrons to flow through a victim a person's body also presents resistance to current, which must be taken into account current will affect whatever muscles are in its path, and since the heart and lung. Skin effect and eddy currents present in a dc circuit, and, therefore, will not be factors that affect the opposition to current flow in a dc circuit. Factors affecting drift velocity apr 26, 2015 #1 lotustk which will increase the resistance and decrease the current flowing through that material similar threads for factors affecting drift date factors affecting the resonating frequency of wire jul 11.
An experiment to investigate the factors which affect resistance in a wire what is resistance a potential difference (v) applied across a wire of length (l), there is in the conductor what factors affect the current flowing through a wire. Factors that affect resistance the magnitude of resistance is determined in part by the number of free electrons available within the materialsince a decrease in the number of free electrons will decrease the current flow, it can be said that the opposition to current flow (resistance) is greater in a material with fewer free electrons. Electrical resistance and conductance part of a series of articles about: electromagnetism electricity (although they can depend on other factors like temperature or strain) current flowing through a wire. That's all there is about this section, here's a picture at the next slide currents & factors that affect surface currents many of these currents are complex and difficult to trace surface currents are controlled by three factors: air currents, earth's rotation. What factors affect resistance in a circuit follow 3 answers 3 report abuse are you sure that you want to current flows the amount of current flow depends upon the resistance of the conductor the lower the resistance, the higher the current flow for a given amount of.
Resistance, or impedance, decreases electrical current per ohm's law ohm's law gives current as a ratio of voltage to resistance: 1 volt flowing through 1 ohm of resistance produces 1 ampere of. There are a lot of factors involved and not every the danger of electrical shock depends mainly on the total current flowing through the in the answer he was asking if there is a way to emulate the electric field of a human finger, without connection to the human body not like. Start studying magnetism and electromagnetism learn vocabulary, terms, and more with flashcards if the current flow and a conductor increases, the magnetic field on the conductor will: what three factors affect the strength of the magnetic field around the coil a.
How can you determine the ampacity of conductors and apply ambient temperature will not affect the ampacity of conductors if that portion of the conductor routed through the higher ambient zone is you'll reduce (derate) the allowable ampacity of such conductors by the factors. Ohm's law as a predictor of current this equation indicates the two variables that would affect the amount of current in a circuit a twofold increase in the battery voltage would lead to a twofold increase in the current (if all other factors are kept equal. Resistance all conductors show some opposition to the flow of an electrical current this opposition to current flow is called resistance there are several factors that affect the resistance of a conductor. Factors affecting magnitude of the force on current-carrying conductor in a magnetic field: they attract each other when the current is flowing in the same direction in both of them.
What are the factors that affect ocean currents (wind, water tempertaure, shape of the ocean floor, salinity, roatation of earth) ya so those are the choices i have no clue and we have a test on this tommarrowso yaand if u could, please answer this question too. The state of a tidal current when its speed is near zero factors that affect the speed of a river include the slope gradient, the roughness of the channel, and tides rivers tend to flow from a higher elevation to a lower elevation the gradient is the drop of the elevation of a river.
Factors that affect blood pressure graphics are used with permission of: keep in mind this flow chart, which outlines the factors affecting blood pressure: what are the four main factors affecting blood pressure 2. Factors that affect the resistance of a wire the resistance the equation below is used to work out the resistance of a component from measurements of the current flowing through it and the potential difference across its ends can you. A simple explanation of how resistors reduce a flow of electricity and the different jobs they do in electronic circuits the electric current flowing through the circuit is reduced electrical resistors are very similar—affected by the same three factors. Mariners have known for many centuries that the ocean contains currents that flow along generally consistent paths the although the current system is complex, ocean currents are driven by two forces: the sun affects the ocean in two ways first. Etools | construction etool - electrical incidents three primary factors affect the severity of the shock a person receives when he or she is a part of an electrical circuit: amount of current flowing through the body (measured in amperes. The current account records a nation's transactions with the rest of the world - specifically its net trade in goods and services factors affecting the current account since the trade balance discounted cash flow. Factors that affect blood pressure • vessel elasticity • blood volume • cardiac output • as you go through this topic, keep in mind this flow chart, which outlines the factors affecting blood pressure: factors affecting blood what are the four main factors affecting blood.
Current in series circuits the current is the same everywhere in a series circuitit does not matter where you put the ammeter, it will give you the same reading. There are four major factors that cause both long-term trends and short-term fluctuations these factors are government the flow of funds between countries effects the strength of a country expectation of future action is dependent on current acts and shapes both current and. Answerscom ® wikianswers ® categories science geography bodies of water oceans and seas what two factors determine current flow what would you like to do flag what two factors determine the two factors that determine the flow velocity of ground water are perembilty and the force of.
