Shift Assistant Interview Questions and Answers

The unit of resistance is ohm.

• The unit of resistance is measured in ohms (symbol: Ω).

• Resistance is the opposition to the flow of electric current in a circuit.

• One ohm is equal to one volt per ampere (1 Ω = 1 V/A).

Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.

• Ohm's law is expressed as V = I * R, where V is the voltage, I is the current, and R is the resistance.

• It helps in calculating the current, voltage, or resistance in a circuit when the other two values are known.

• For example, if a circuit has a voltage of 12 volts and a resistance of 4 ohms, the current f...read more
