In electrical fittings, a wire is connected to ground. The reason for this is
In electrical fittings, a wire is connected to ground primarily to provide a safe path for electrical current in case of a fault, such as a short circuit. This connection directs excessive current away from sensitive equipment and prevents electric shocks by creating a low-resistance path to the earth.

The correct answer is: If a short circuit occurs, the current will go into the ground (option A). Connecting a wire to ground in electrical fittings serves as a safety measure. In the event of a fault like a short circuit, where an unintended connection between live and neutral wires occurs, excess current flows through the ground wire to the earth. This action helps prevent damage to appliances, overheating of wires, and reduces the risk of electric shocks to people. Grounding does not eliminate electricity loss nor does it directly complete an electric circuit; its primary purpose is safety by providing a low-resistance path to dissipate fault currents harmlessly into the ground. Additionally, grounding does not remove fluctuations in electricity; this is managed through voltage regulation and stabilizing devices in electrical systems.
