What is another term for electric pressure________?
Show answer Hide answer
Answer: C. voltage
Explanation
Voltage represents the electrical potential difference that drives charge carriers through a circuit. It acts as an electrical pressure pushing electrons along conducting pathways. This pressure is measured in volts across circuit nodes and power supplies. Electrical pressure is a common hydraulic analogy used to explain voltage in circuits. Higher voltage pushes more current through a given resistance according to Ohm law. Voltage sources maintain this potential difference to sustain continuous charge flow.
Voltage concepts help technicians diagnose faults in electrical and electronic equipment. Power grids step up voltage to high levels to reduce losses during long-distance transmission. Understanding electrical pressure is fundamental for analyzing closed circuit behavior. Option A is incorrect because resistance opposes rather than drives current flow. Option B is wrong since power is the rate of energy transfer rather than electrical pressure. Option D is incorrect because energy represents total capacity to do work over time.
