Question

identify the voltage source in this circuit. battery resistor switch bulb legend a battery b fuse c switch d bulb e conductor

Explanation:

A battery is a device that stores chemical energy and converts it into electrical energy, providing the potential difference (voltage) needed to drive current in a circuit. Resistors limit current, switches control the flow of current, and bulbs convert electrical energy into light energy. They are not voltage - sources.
