Question

Differentiate between circuit and Voltage

Answer 1

The terms "circuit" and "voltage" refer to different aspects of electrical systems. Here's how they differ:

Circuit

• Definition: A circuit is a closed path through which electric current flows. It consists of components like resistors, capacitors, inductors, switches, and a power source.
• Purpose: Provides a route for electricity to move from a power source, through various devices, and back to the source.
• Example: A flashlight circuit includes a battery, a switch, and a bulb connected in a loop.

Voltage

• Definition: Voltage, also known as electrical potential difference, is the force that pushes electric charges through a circuit. It is the measure of the energy per unit charge.
• Purpose: Acts as the driving force for current flow within a circuit.
• Unit: Measured in volts (V).
• Example: A 9V battery provides a 9-volt potential difference between its terminals.
