 An analogy can be drawn between the formulae related to a capacitor and inductor. Observe the similarity in various quantities that are related to the two.









Example:

To obtain a displacement current of 1 A across the plates of a 2 µF capacitor, the voltage across it should be varied at the rate of



Answer:

The expression for displacement current through a capacitor is



Here, C is the capacitance and  is rate of change of capacitor voltage.

Substitute the known values.

Pacemaker! How does it works?

  The consistent beating of heart is the very basic process, which keeps all of us alive on this beautiful planet. Unfortunately, some people develop heart problems in their old age. This makes their heart beat slower and inconsistent. It happens due to problems in the sinoatrial node. Sinoatrial node is a part of heart, which sends electrical signals to heart. These electrical signals are vital to make the heart function properly. In order to make heartbeats consistent, pacemaker is used. Pacemaker is a device with the following components. 1. A battery 2. A microprocessor control switch 3. An RC circuit Let us understand how this pacemaker works. The battery charges the capacitor present in the RC circuit. Then, a computer-controlled switch disconnects the battery and connects the charged capacitor with the heart by a wire. This gives a pulse to the heart and it regains the desired beating frequency. After the capacitor is discharged, the computer-controlled switch disconnects t...
