What is the analogy between mechanical and electrical systems?
Electrical systems and mechanical systems are two physically different systems. There are two types of electrical analogies of translational mechanical systems. Those are force voltage analogy and force current analogy….Torque Current Analogy.
| Rotational Mechanical System | Electrical System |
|---|---|
| Angular velocity(ω) | Voltage(V) |
Why mechanical system are studied using electrical analogy?
The through and across analogy between the electrical and mechanical domain is the same as in the mobility analogy….Impedance analogies.
| Type | Elements |
|---|---|
| Mechanical translation variable | Mass |
| Mechanical rotation variable | Moment of inertia |
| Analogous electrical variable | Inductance |
How the electro mechanical systems are defined as analogous systems?
Definition: Electrical and mechanical systems possess fixed analogy and there exist similarity between the equilibrium equations of the two. This allows forming such electrical systems whose behavioural characteristics are similar to the given mechanical system. Such systems are known as analogous systems.
What are the analogies for electrical parameters current?
So for this analogy, remember:
- Water = Charge.
- Pressure = Voltage.
- Flow = Current.
What is analogy system?
A precise definition is given for the analogy of a dynamical system to another system (or subsystem thereof). An analogy between two physical systems is a correspondence between them which preserves dynamical properties. Thus, the dynamics of any system can be read off by a study of any of its analogs.
What is the water analogy for electricity?
The water/hose analogy for electricity is useful for explaining voltage, current, and power. In general terms, charge is water, voltage is the pressure of water, current is the flow of the water. Power is the total amount of water flowing in given time.
