Two sinusoidal voltage of the same frequency are shown in the diagram. What is the frequency, and the phase relationship between the voltage?

Frequency in `Hz` phase lead of `N` over `M` in radius

A

`{:("Frequency in Hz Phase lead of N over M in radians"),(" 0.4 "- pi // 4 ):}`

B

`{:("Frequency in Hz Phase lead of N over M in radians"),(" 2.5 "- pi // 2 ):}`

C

`{:("Frequency in Hz Phase lead of N over M in radians"),(" 2.5 "+ pi // 2 ):}`

D

`{:("Frequency in Hz Phase lead of N over M in radians"),(" 2.5 "- pi // 4 ):}`

Text Solution

Verified by Experts

The correct Answer is:
B
Since, M lead by N by an angle of `pi//2`
`:.` Phase lead of N over M in radians `= - (pi)/(2)`
and `f = (1)/(T) = (1)/(0.4) = 2.5 Hz `
