What is Ohm's law?
Q: What is Ohm's law?
A: Ohm's law states that in an electrical circuit, the current passing through a resistor is related to the voltage difference and the electrical resistance between the two sides, as long as the physical conditions and temperature of the conductor remain constant.
Q: How can Ohm's law be written?
A: Ohm's law can be written in three ways depending on which variable is placed on the left of the equals sign: I = V/R, V = IR or R = V/I.
Q: What does I stand for?
A: I stands for current in amperes.
Q: What does V stand for?
A: V stands for potential difference in volts.
Q: What does R stand for?
A: R stands for resistance, measured in ohms.
