What term is defined as the measure of electrical pressure in a circuit?

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

Answer: (A)

Voltage is the measure of electrical pressure in a circuit. It represents the potential difference that pushes charges to move through the circuit, producing current when a path is complete. This quantity is what drives electrical flow, and it is measured in volts. In contrast, current is the actual flow of electric charges, resistance is the opposition to that flow, and power is the rate at which electrical energy is transferred or used. Ohm’s law links them by stating voltage equals current times resistance, showing how higher voltage increases the pushing force that drives current.
