with an example explain how to calculate the amount of electricity an appliance will use
Solution,
Amount of electricity consumed by an electric appliance can be determined by recording the current (I) flowing through it with the help of an ammeter.
In household circuitry, the voltage (V) applied is 220 V. The potential difference applied across the electric appliance can also be determined using a voltmeter.
If we know how long the appliance is drawing current, i.e., how long (t) the appliance is kept ON, then the product
will give the amount of electrical energy consumed by the electric appliance.
