Question

Define the Resistance,inductance,capacitance?

Answer 1

Explain the following terms-

a) Capacitance

b) Inductance

c) Resistance

a) Capacitance: The amount of charge that can be stored inside a capacitor at a given voltage is called Capacitance. It gets charged when charges are forced into the positive (or upper) plate of the capacitor due to emf. Similarly, it discharged when charges are forcefully pulled out of the capacitor. Capacitance is measured in Farad.

b) Inductance: It is the property of a coil to resist any change in electric current flowing through it. Self inductance is caused when a coil resists the current change through itself. Mutual inductance occurs when a secondary coil opposes current change in a primary coil. Inductance is measured in Henry.

c) Resistance: It is the property of a material which opposes the flow of electric current through it. Conductors have low resistance while insulators have very high resistance. It is measured in Ohms.

Answer 2

Answer:

RESISTANCE:

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.

INDUCTANCE :

In electromagnetism and electronics, inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. The flow of electric current through a conductor creates a magnetic field around the conductor, whose strength depends on the magnitude of the current.

CAPACITANCE :

Capacitance is the ratio of the change in electric charge of a system, to the corresponding change in its electric potential. There are two closely related notions of capacitance: self capacitance and mutual capacitance. Any object that can be electrically charged exhibits self capacitance.
