Root mean square voltage,
Vpeak = 170 V
What is the rms value Vrms of the voltage plotted in the graph?
When a lamp is connected to a wall plug, the resulting circuit can be represented by a simplified AC circuit, as shown in the figure. Here the lamp has been replaced by a resistor with an equivalent resistance R = 120 Ω. What is the rmsvalue Irms of the current flowing through the circuit?
What is the average power Pavg dissipated in the resistor?
