Question

You have the questions and their solutions. You need to write different way of answers, now you have enough time, and time should not be an issue for you.

Problem 1

Find the Power(P) and Q for the given Voltage and current.

a) V = 100∠-45^oV, I = 20∠15^oA

b) V = 100∠-45^oV, I = 20∠165^oA

c) V = 100∠-45^oV, I = 20∠-105^oA

d) V = 100∠0^oV,  I = 20∠120^oA

Problem 2

For v(t) = 3cos(ωt + 25^o) and i(t) = 5 sin(ωt -65^o), compute the power factor and reactive factor.

Problem 3
