A voltage is given by vt10sin1000pit 30 degreesv 1 use a


a voltage is given by v(t)=10sin(1000(pi)(t) + 30 degrees)V

1. use a cosine function to express v(t) in terms of t and the constant pi

2. find the angular frequency

3. find the frequency in hertz to two significant figures and appropriate units

4. find the [hase angle

5. find the period

6.find Vrms

7. find the power that this voltage delivers to a 60(ohm) resistance

8. find the first value after t=0 that v(t) reaches its peak value
