Current​

Answer 1

✻Answer✻

In an AC circuit, the voltage at time t is given be

v=Asin(ωt+Φ)

Here, A is the amplitude

ω is the angular frequency.

Φ is the phase difference

Substituting the values in the given equation ie v=200sin314t,we get:-

A=200

ω=314

Φ=0

Now, we know that ω=2πf

Here, f is the required frequency.

Thus:

314 = 2 x π x f

Putting π = 3.14, we get

314 = 6.28 x f

f= 50 Hz

Hence, frequency of the AC current is 50Hz
