Question

The equivalent quantity of mass in electricity is ?

Answer 1

Here in order to answer the question we will recall which quantity is equivalent to mass in electricity and how is it equivalent to mass and we will see the definition of that quantity as well.

Complete answer:
Electrical circuits have an intrinsic property called inductance. If we like it or not, it will still be contained in an electrical circuit. Greater inductance refers to a circuit in which a strong emf is caused when the current in the circuit shifts.A straight wire carrying current with no iron parts in the circuit will have a lower value of inductance, while a circular coil with several turns will have a higher induced emf to oppose the cause, and hence the circuit will have a higher value of inductance.

Inductance is a property of an electric conductor or circuit that causes an electromotive force to be produced as a result of a change in the current flowing. There are two different forms of analogies.
Voltage of force: In this example, mechanical force is thought to be the same as voltage in an electrical device.
-Mass (M) = Inductance (L)
-Resistance (R) = Frictional Coefficient (B)
-Spring Constant (K) = Capacitance Reciprocal (1c)
-Charge (q) = Displacement (x)
-Current (i) = Velocity (v)

Analogy of Force and Current: In this analogy, mechanical force is considered to be current in an electrical device.
-Capacitance (C) = Mass (M)
-Resistance reciprocal (1R) = Frictional coefficient (B)
-Spring constant (K) = Inductance Reciprocal (1L)
-Magnetic Flux () = Displacement(x)
-Voltage (v) = Velocity (V)

Hence, the equivalent quantity of mass in electricity is inductance.

Note: The inductor's self-inductance is known as the "inertia of electricity." The name comes from the fact that, similar to how mass opposes changes in an object's motion (velocity), an inductor's inductance opposes changes in current flowing through it.
