Ohm’s and Kirchhoff’s Laws – Study Material
Ohm’s law defines When the temperature remains constant, current flowing through a circuit is directly proportional to potential difference across the conductor.
- Ohm’s Law
- Kirchhoff’s Laws
- When the temperature remains constant, current flowing through a circuit is directly proportional to potential difference across the conductor.
- Kirchoff’s Voltage Law: The algebraic sum of all branch voltages around any dosed loop at a network is zero at all instant of time.
Kirchoff’s Current Law (KCL): “Sum of the currents entering a node is same as the sum of the currents leaving the node”.
- When a time varying current passes through a circuit varying flux is produced. Because of this change of flux, voltage is induced in the circuit proportional to the time rate of change of flux or current.
- A capacitor is a circuit element that, like the inductor, stores energy during periods of time and returns the energy during others.
- In the capacitor, storage takes place in an electric field unlike the inductance where storage is in a magnetic field. A capacitor is formed by two parallel plates separated by an insulating medium.
