2. Enables us to check if device is

working or not

Resistance-

The quantity which opposes the flow of

current is called resistance.

Use of Resistance-

1. It is used to control a speed or

functioning of any device.

Eg-By rheostat, we control speed of fan.

2. It helps to calculate the Voltage and

Current.

Eg. We ammeter has zero resistance

where as voltmeter has infinite

resistance.
