What is the electrical analogue of inertia?
Self-inductance of an inductor is referred to as the ‘inertia of electricity’. The reason it has been called as such is because just as how mass opposes the change in the motion (velocity) of an object, the inductance of an inductor opposes the change in current flowing through it.
What is electromagnetic analogue of mass in mechanics?
Self inductance plays the role of inertia, which is the electromagnetic analogue of mass in mechanics.
What is mass in electrical system?
If Electricity means drift flow of electrons, then mass of electricity means mass of electrons. Mass of electrons are known. So mass of electricity are also known.
What is the analogue of mass in force current analogy?
In Force-Voltage Analogy: Velocity is analogous to current….4.6.
| Force analogy | Voltage analogy | Current analogy |
|---|---|---|
| Mass (M) | Inductor (L) | Capacitor (C) |
| Spring Constant (K) | 1/C | 1/L |
| Damper (B) | R | 1/R |
| Displacement (x) | Charge (Q) | Flux (ϕ) |
What is electrical analogous of a gear?
Mechanical–electrical analogies are developed by finding relationships between variables in one domain that have a mathematical form identical to variables in the other domain. The impedance analogy makes force and voltage analogous while the mobility analogy makes force and current analogous.
What is electrical domain?
In the electrical domain, the main signal bearing entities are voltage and their current in circuit environments. Electrical fields (electromagnetic and electrostatic) carry the signals in wireless media.
What is the analogue of force constant in electrical system?
In force voltage analogy, the mathematical equations of translational mechanical system are compared with mesh equations of the electrical system….Force Voltage Analogy.
| Translational Mechanical System | Electrical System |
|---|---|
| Spring Constant(K) | Reciprocal of Capacitance (1c) |
| Displacement(x) | Charge(q) |

|---|---|---|
| Capacitance, C | Mass, M | Compliance, 1/K (Inverse spring constant) |
| Inductance, L | Compliance, 1/K (Inverse spring constant) | Mass, M |

Is mechanical analog?
An analog computer or analogue computer is a type of computer that uses the continuously variable aspects of physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved.
What is electrical analog of spring constant?
This result is identical in form with that for the mass on a spring. Therefore the electrical system and the mechanical system are said to be analogous. That is, displacement is equivalent to quantity of electrical charge, mass to inductance, and spring constant to the reciprocal of capacitance.
