Question

b) Calculate the frequency of an alternating current if the
direction changes after every 0.01sec?​

Answer 1

Answer:

50

Explanation:

n=1/t

here,t=0.02s

t=time period .

so n=50Hz

Answer 2

50Hz

2×0.01s =T

because the direction will change only after every half time period

1/T = 1/0.02s = 50Hz
