GEOLOGY

Detailed explanation-1: -Current flows through the wires. A light bulb provides resistance in the circuit.

Detailed explanation-2: -Resistors are electronic components that resist the flow of electricity in a circuit. Resistors are used in electric circuits to adjust current and voltage, in much the same way as faucets are used to adjust the flow of tap water.

Detailed explanation-3: -The power rating P and voltage rating V of a bulb is marked over the bulb. The resistance of the bulb is found theoretically using the formula R=V2/P R = V 2 / P .

Detailed explanation-4: -When a light bulb connects to an electrical power supply, an electrical current flows from one metal contact to the other. As the current travels through the wires and the filament, the filament heats up to the point where it begins to emit photons, which are small packets of visible light.

Detailed explanation-5: -As electrons move through the conductor, some collide with atoms, other electrons, or impurities in the metal. It is these collisions that cause resistance.
