Sagot :
The instantaneous value of a sinusoidal waveform is the value of the alternating function at any particular instant.
The instantaneous value of a 10 ampere peak sine wave at 0, 30, 45, 60, and 180 degree are 0 A, 5 A, 7.07 A, 8.66 A, 0 A respectively.
From the question,
Instantaneous value is given as 10 A
The instantaneous value of a sine waveform is determined by the relation,
Instantaneous value = Peak value x sin θ
Substituting values in the above equation;
For 0°⇒
instantaneous value = 10 x sin 0°
= 10 x 0
= 0 A
For 30°⇒
instantaneous value = 10 x sin 30°
= 10 x (1/2)
= 5 A
For 45°⇒
instantaneous value = 10 x sin 45°
= 10 x (1/√2)
= 10 x 0.707
= 7.07 A
For 60° ⇒
instantaneous value = 10 x sin 60°
= 10 x (√3 / 2 )
= 10 x 0.866
= 8.66 A
For 180° ⇒
instantaneous value = 10 x sin 180°
= 10 x 0
= 0 A
Hence the instantaneous value of a 10 ampere peak sine wave at 0, 30, 45, 60, and 180 degree are 0 A, 5 A, 7.07 A, 8.66 A, 0 A respectively.
