-What is the rms value V_rms of the voltage plotted inthe graph?

When a lamp isconnected to a wall plug, the resulting circuit can be representedby a simplified AC circuit, as shown in the figure. (PartB figure) Here the lamp has been replaced by a resistorwith an equivalent resistance = 120 $\Omega$ . What is the rmsvalue I_rms of the current flowing throughthe circuit?
