Two resistors 30 Ω and 50 Ω are connected in parallel and this parallel arrangement is then connected in series with two resistors 20 Ω each. The combination is placed across a 10V potential difference. Hence construct the diagram of the above circuit. According to your observation evaluate the total current in the circuit and also the total power delivered to the resistors and also show that the total power dissipated is equal to the sum of the power dissipated by individual resistor. Also, can you suggest the current through 30 Ω resistance?
