Question

While testing an LED, it is advised not to close the circuit for a long time because the ___________.

• A. LED can get damaged
• B. wires will burn up
• C. cells of the battery will drain very quickly
• D. circuit gets overloaded

Answer 1

The correct option is C cells of the battery will drain very quickly

When the circuit is closed, charges start flowing from one end to the other.

While checking the LED, the circuit should not be closed for a long time because the cells of the battery will drain very quickly as LED offers very little resistance to the flow of current.
