Question

When we are inserting the battery into our devices, then we have to match + and - signs with the respective electrodes correctly.

• A. True
• B. False

Answer 1

The correct option is A

True

When we insert the battery into our devices matching these '+' and '-' signs, we complete a circuit and that is how the circuit gets its power. For example, a torch bulb operates when the switch is used to turn it on or off. The same marks are present on the torch we put our batteries into.
