Draw a circuit with a battery of 90 V is connected to fourresistors, R1 =10 Ω, R2,= 20 Ω , R3 =30 Ω andR4= 40 Ω, as follows. Resistors R1 andR2 are connected in parallel with each other, resistorsR3 and R4 are connected in parallel with eachother, and both parallel sets of resistors are connected in serieswith each other across the battery.
