- Statement I is false: In an AC circuit with a frequency of 60 Hz, the current completes 60 cycles per second. In each cycle, the current direction reverses twice (passing through zero from positive peak to negative peak, and then from negative peak to positive peak). Therefore, the current changes direction 2 60 = 120 times per second, not 60 times. If the frequency were 50 Hz (standard in India), it would change direction 100 times per second. So, Statement I is false regardless of whether the frequency is 50 Hz or 60 Hz. - Statement II is true (in context): The statement says the frequency of alternating voltage supplied is 60 hertz. While the standard frequency in India is 50 Hz, in many countries (like the USA), the standard frequency is 60 Hz. This statement is true if referring to an electrical system operating at 60 Hz.
