The voltage supplied by a wall socket varies with time, reversing its polarity with a constant frequency, as shown in the graph. (Figure 1)
What is the rms value Vrms of the voltage plotted in the graph?

When a lamp is connected to a wall plug, theresulting circuit can be represented by a simplified AC circuit, asshown in the figure. (Part B figure) Here the lamp has been replaced by a resistor with an equivalentresistance Part B figure) Here the lamp has been replaced bya resistor with an equivalent resistance R = 120 . What is the rms value Irms of the current flowing through the circuit?

Express your answer in amperes.

Irms = ? A

3.

What is the average power Pavg dissipated in the resistor?

Express your answer in watts.

Pavg = ? W
