FAQs

If a fuse blows, it breaks the circuit and stops the flow of current, protecting the appliances and preventing overheating or fire hazards. The fuse must be replaced to restore the connection.

Alternating current (AC) is used for domestic supply because it is more efficient for transmitting electricity over long distances. AC can be easily transformed to different voltage levels, which reduces energy losses in transmission.

A fuse is a one-time safety device that melts and breaks the circuit if excess current flows. An MCB (Miniature Circuit Breaker) automatically trips during overload or short circuits but can be reset after the fault is corrected.

The earth wire provides a low-resistance path for leakage currents to flow into the ground. It protects users from electric shocks by safely directing excess current away from the appliance in case of a fault.

Appliances are connected in parallel in domestic circuits to ensure that each receives the same voltage and operates independently. This setup also allows individual control of devices, so if one appliance fails, the others continue to function.
