At time t = 0 second, voltage of an A.C. Generator starts from 0V and becomes 2V at time t = 1 100 π second. The voltage keeps on increasing up 100V, after which it starts to decrease. Find the frequency of the Generator.

Question

At time t = 0 second, voltage of an A.C. Generator starts from 0V and becomes 2V at time t = 1 100 π second. The voltage keeps on increasing up 100V, after which it starts to decrease. Find the frequency of the Generator., 100 Hz, 1 Hz, 2 Hz, 5 Hz
