A RC series circuit ($R_1=40\ \Omega$, C=10µF) and RL series circuit ($R_2=50\ \Omega$ and L=0.2H) are connected in parallel to each other and a source of 100V, 50Hz is applied across the overall circuit. Calculate,
i) Current drawn by RC branch, RL branch and overall current taken from supply.
ii) Construct phasor diagram.
