What is the pressure in an electrical circuit?

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

Answer: (A)

The pressure in an electrical circuit is voltage. Voltage is the potential difference that pushes electric charges to move through conductors. It’s like water pressure that drives flow through a pipe—the higher the voltage, the greater the push on charges. This driving force is what determines how much current can flow through a given resistance, as described by Ohm’s law: V = I × R. Current is the actual flow of charges, resistance is the opposition to that flow, and power is the rate at which energy is transferred. So the pressure you’re asking about is voltage.
