Question

an altemting vtage is given by e=6 sin 314tt find peak value and frequency

Answer 1

Answer:

Here's your answer

Explanation:

e=6sinωt+8cosωt

⟹e=6cos(ωt−90)+8cosωt

Taking maximum values

⟹e=6∠−90+8∠0

⟹e=6cos90−6jsin90+8

⟹e=8−6j

⟹e=10∠−36.86

⟹e=10cos(ωt−36.86)

So, maximum or peak value =10
