Question

An electrified needle is used to burn off warts, with the circuit being completed by having the patient sit on a large butt plate. Why is this plate large?

Short answer

The plate is an excellent conductor with low resistance, and the circuit's total resistance is lowered.

Step-by-step solution

Definition of Electricity

The presence and flow of electric charge are defined as electricity. We can transmit energy using electricity in ways that allow us to perform simple tasks.

The movement of electrons via conductors such as copper wires is the most well-known example. The term "electricity" is sometimes used to refer to "electrical energy."

Explanation

As the human body is a poor conductor of electricity, a big butt-plate is utilized to enhance the body's contact surface with a good conductor, lowering total resistance.

Because a current flows through the path with the least resistance, a larger plate provides more channels for the charge to move through the body.
