Voltage across Inductance Calculator

Voltage across Inductance Calculator

Voltage across inductance calculator is used to find the voltage drop of the inductor in an electrical circuit.

What is the voltage across an inductance?

If current flows through an inductor it generates a magnetic field around the inductor. Changes in the rate of current with the passage of time generate a voltage across the inductor.

According to Faraday’s law of electromagnetic induction in a change of magnetic field through a closed loop of wire induces a voltage in the wire. In the inductor, the induced voltage opposes any changes in the current flowing through it.

Formula of voltage:

V = (L × I)/T

Where,

• V = total voltage across the inductor
• L = inductance of the inductor
• I = rate of change of current
• T= time of the changing current

How to evaluate the voltage across the inductor:

Example 1:

An inductor working in a DC Circuit with an inductance of 2, a rate of change of current is 20 in 2 seconds then find the voltage across the inductor.

Solution:

Step 1:

Write the data from the above question.

Inductance = L = 2, rate of current = I = 20, Time = T = 2, V=?

Step 2:

Write the formula to calculate the voltage across the inductor.

V = (L × I)/T

Step 3:

Apply the values in the above formula.

L = 2, I = 20, T = 2

V = (L × I)/T

V = (2 × 20)/2

V = (40)/2

V = 20 volt

Therefore, the voltage across the inductor is 20 volts.

Example 2:

An inductor working in an AC Circuit with an inductance of 6, a rate of change of current is 25 in 5 seconds then find the voltage across the inductor.

Solution:

Step 1:

Write the data from the above question.

Inductance = L = 6, rate of current = I = 25, Time = T = 5, V=?

Step 2:

Write the formula to calculate the voltage across the inductor.

V = (L × I)/T

Step 3:

Apply the values in the above formula.

L = 6, I = 25, T = 5

V = (L × I)/T

V = (6 × 25)/5

V = (150)/5

V = 30 volts

Therefore, the voltage across the inductor is 30 volts.
