Ravel Electronics Electrician Interview Questions and Answers

Voltage is the electric potential difference between two points in an electrical circuit.

• Voltage is a measure of the force that pushes electric charges through a circuit.

• It is measured in volts (V) and represents the potential energy per unit charge.

• Voltage can be thought of as the pressure or intensity of the electric field.

• Higher voltage means more potential energy and a greater ability to do work.

• For example, a batt...read more

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

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

• It helps in calculating the current, voltage, or resistance in a circuit.

• For example, if a circuit has a voltage of 12 volts and a resistance of 4 ohms, Ohm's law ca...read more
