## What is centripetal velocity formula?

The centripetal velocity formula is given by: $$v = r\omega$$ where: v is the centripetal velocity in meters per second (m/s) r is the radius of the circular path in meters (m) ω (omega) is the angular velocity in radians…

## Dimensional formula for displacement current

Displacement current is defined as: $$I_d = \varepsilon_0 \frac{d\phi_E}{dt}$$ Where: I_d is the displacement current (in amperes) ε_0 is the electric constant, also known as the permittivity of free space (in farads per meter) Φ_E is the electric flux (in…

## Is displacement current a real current?

The displacement current is not a “real” current in the sense that it does not describe charges flowing through a region. It behaves, however, exactly like a real current. When we have a changing E field, we can treat its…

## What is displacement current formula?

The formula for the displacement current is: $$I_d = ε_0 \frac{d\phi_E}{dt}$$ Where: I_d is the displacement current (in amperes) ε_0 is the electric constant, also known as the permittivity of free space (approximately 8.85 × 10^−12 F/m) Φ_E is the…

## What is called displacement current?

Displacement current is a concept in electromagnetism that describes the flow of electric charge that occurs due to a changing electric field in a region of space. It was first introduced by James Clerk Maxwell as part of his famous…

## What is displacement current and its properties?

Displacement current is the flow of electric charge in a vacuum or dielectric material that is caused by a changing electric field. It is a time-varying electric field that acts like an electric current and produces a magnetic field, just…

## How a transformer works?

A transformer works on the principle of electromagnetic induction, which states that a changing magnetic field induces an electromotive force (EMF) in a conductor. A transformer consists of two coils of wire, known as the primary and secondary winding, which…

## What is efficiency of transformer?

The efficiency of a transformer is a measure of how effectively the transformer can transfer electrical power from the input circuit to the output circuit. It is defined as the ratio of the output power to the input power, and…
