total R = 50 + 40 + 30
current = voltage / total R
v drop = current * resistance
Three resistors of resistance 50,30,40 ohms are connected in series across 100V suppliers.
(I).Draw circuit
(II).Calculate the total resistance.
(III).Total current flowing through the circuit.
(v). Voltage drop across each resistor.
