Question

When an AC source is connected across a 22.0 resistor, the output voltage is given by v = (120 V)sin(70t). Determine the following quantities.

Part (e): Find the current when t = 0.0045 s.

When an AC source is connected across a 22.0 resistor, the output voltage is given by Av = (120 V)sin(70t). Determine the following quantities. (a) maximum voltage 120 (b) rms voltage 84.85 (c) rms current 3.86 (d) peak current 5.45 (e) Find the current when t = 0.0045 s 0257 Did you use the correct units for the argument of the sine function? A

Explanation / Answer

v = (120 V)sin(70t)

current at  t = 0.0045 s

v/r = (120 V)sin(70*0.0045) /22 = 4.559 amp
