What is potential difference commonly called?

• A. Current
• B. Voltage
• C. Resistance
• D. Power

Answer: (B)

Potential difference is what drives electric charges to move and is commonly called voltage. It represents the difference in electric potential energy per unit charge between two points in a circuit, and it’s what a source like a battery provides to push charges through conductors and components. Measured in volts (symbol V), voltage is the driving force that, together with the circuit’s resistance, determines how much current flows (as described by V = I R). Understanding this helps connect how energy is moved around a circuit: the higher the potential difference, the greater the push on charges. The other terms describe different aspects: current is how much charge flows per second, resistance is how much a component opposes that flow, and power is the rate at which energy is transferred.
