Question

A resistance and inductance are connected in series across a voltage, V=283sin314t The current is found to be 4sin(314t-pi//3). Find the value of the inductance and resistance.

Answer 1

The answer for your question is 70.75 ohms resistance in series.

We know resistance is the opposition to flow. It is defined as the ratio between the applied voltage to the current flowing through the circuit.

We need to find the resistance which is connected in series.

We know, R= V°/I°

Here, in this question,

V°=283

I°=4

Therefore,

R=V°/I°

=283/4= 70.75 ohms.
