If the phase shift is π/2 rads and T is the period, then the voltage at (T/2) is a. zero
b. +peak/2
c. +peak
d. -peak

d. - peak

Explanation:

In alternating current, the voltage is represented by the following formula:

where,

=Maximum voltage

=Angular frequency

=phase shift

t=time

The angular frequency can be written in terms of the period (T), so:

So the equation will now lok like this:

we know that and that so the equation will now look like this:

which can be simplified to:

Which solves to:

so the answer is d. -peak
