Alternating Current and Voltage

Q1:

A sawtooth wave has a period of 10 ms. Its frequency is

A 10 Hz

B 50 Hz

C 100 Hz

D 1,000 Hz

ANS:C - 100 Hz

Period = 1/frequency.
10ms = 1/frequency.
Frequency = 1/10ms.
Frequency= 1/10*10^-3.
So,
Frequency = 10^3/10.
Frequency = 1000/10.
Frequency = 100 Hz.
