Question
How was question (g) calculated? I keep trying to replicate my answer but I can't seem to come to the right answer!
The output voltage of an AC generator is given by deltav = (100 V)sin(70Pit). The generator is connected across a 17.0-Ohm resistor. (a) By inspection, what is the maximum voltage? (b) By inspection, what is the frequency? (c) Find the rms voltage across the resistor. (d) Find the rms current in the resistor. (e) Find the maximum current in the resistor. (f) Find the power delivered to the resistor. (g) Find the current when t = 0.0050 s.Explanation / Answer
g) at t = 0.005
delta V = 100*sin(70*pi*0.005)
= 45.95 volts
so, I = delta V/R
= 45.95/17
= 2.7 A
