Question

You doubled the voltage frequency in an RL series AC circuit, the inductive resistance would?

Answer 1

Answer:

When the voltage frequency is doubled, the resistance will remain same in RL series AC circuit.

Explanation:

A circuit that has an inductance L and Resistance R is said to be a RL or LR circuit. The inductance in the circuit is directly proportional to the Frequency F and Inductive Reactance XL of the circuit.  

$\mathrm{XL}=2 \times \pi \times \mathrm{F} \times \mathrm{L}$

So, whenever there is a change in the frequency it directly changes the inductance and inductive reactance of the circuit but Resistance will remain unaffected.

Resistance in a RL circuit is independent of the frequency. Therefore, in the given case, the resistance will remain the same only the reactance will get doubled.

Answer 2

Answer:

Remain the same.

Explanation:

If you doubled the voltage frequency in an RL series AC circuit, the inductive resistance would remain the same.
