In a series RLC circuit, potential difference across R,L and C are 30V,60V and 100V respectively as shown in figure. The emf of source (in volts)is:
Two resistors of resistance 3Ω and 6Ω are in parallel and the combination is in series with a 4Ω resistor. A potential difference of 90V is applied across the network. The potential difference across the 4Ω and the current in the 3Ωresistor are respectively,
