Checking Energy Stored in a Capacitor Using Joulemeter

We all have different kind of fans in our house.

The rotating blades of a fan provides air.

But how the blades of a fan rotates to give us air.

A motor is fitted inside the fan which rotates the blade of fan.

And to maintain the good speed of the blades a capacitor is used in a fan.

A capacitor is an electronic component that stores electrical energy in an electric field.

The capacitor provides the energy stored to initiate the movement of blades of the fan

But how the energy stored in capacitor is measured.

the energy stored by a capacitor can be measured by a device called a Joulemeter.

Let's measure the energy stored in a capacitor with the help of joulemeter

We have a capacitor which is charging by connected to a battery of voltage .

The capacitor is charged to the voltage and we closed the circuit.

Now we connected the capacitor to the joulemeter to find the energy stored in the capacitor.

Also we connected a V bulb to joulemeter to find the energy stored .

And we observed the reading of the joulemeter to find the energy.

Now we can calculate the energy using the formula of energy in capacitor.

here we observed that energy measured in both the cases is equal.

Revision

A capacitor is an electronic component that stores electrical energy in an electric field.

Joulemeter is device that is used to measure the energy stored in a capacitor.
