Assume an ideal power supply. The graph shows the voltage across the source (red) and the current through the circuit (blue) as functions of time (voltage is given in volts, current is given in milliamperes [10^-3 amperes], and time is given in seconds). Restart. For each circuit,

What is the rms voltage? What is the rms current? What is the value of the unknown resistor? What is the average power dissipated?
