Question

when 10v are applied to an ac circuit ,the current flowing in it is 100mA. find impedance?​

Answer 1

Explanation:

So for a purely resistive circuit, the alternating current flowing through the resistor varies in proportion to the applied voltage across it.

Answer 2

Question :

When 10v are applied to an ac circuit ,the current flowing in it is 100mA. Find impedance?

Answer :

The impedance is 100 v/A

Given :

Potential Difference = 10v

Current = 100mA

To find :

Impedance

Solution :

We know that,

Z( Impedance ) = Potential Difference( v ) / Current ( A )

We also know that ,

1 A = 1000 mA

Hence, 1 mA = 1/1000 A

100 mA = (1/1000) × 100 A

= 1/10 A

Therefore, Z = 10 / (1/10)

Z = 10 × 10

Z = 100

Hence, Impedance is equal to 100 v/A.
