How To Determine Voltage Across Resistor

How To Determine Voltage Across Resistor. V(t) is sinusoidal voltage with peak v m and time period t. So, over here, notice, i know the current is five, the resistance is two, v equals ir, so the voltage here must be 10 volts.

Solved In The Circuit Shown, A) Calculate The Current Del from www.chegg.com

And similarly, the voltage across this resistance, ir, five times eight, must be 40 volts. We have a resistor and an ac voltage v, represented by the symbol ~, that produces a potential difference across its terminals that varies sinusoidally. Source voltage, voltage drop, current, and color of leds determine the value of the resistor.
