For the circuit shown in the diagram given below


Calculate:


(i) the value of current through each resistor.


(ii) the total current in the circuit.


(iii) the total effective resistance of the circuit.

(i) Here R1= 5 ohm, R2= 10 ohm and R3= 30 ohm

The value of current through each resistor is different as they are arranged in parallel connection.


So the current through 5 ohm resistor, I1 = V/R = 6/5 = 1.2A


So the current through 10 ohm resistor, I2 = V/R = 6/10 = 0.6A


So the current through 30 ohm resistor, I3 = V/R = 6/30 = 0.2A


(ii) The total current in the circuit = I= I1+ I2+ I3


1.2A + 0.6A + 0.2A = 2A


(iii) Total resistance in the circuit = R, As the circuit is in parallel connection, so




R= 3 ohm
