Question

Figure shows the circuit diagram of three resistors R_1, R₂, R₃ connected in parallel to a 6 V battery. If the values of resistance of resistors R_1, R_2, R₃ are 5 Ω, 10 Ω, 30 Ω respectively; calculate:

(i) the value of current through each resistor.
(ii) the total current in the circuit.
(iii) the total effective resistance of the circuit.

Answer 1

(i) In parallel the potential difference across each resistance remains the same.

(ii) In parallel combination of resistors, the current is additive.

(iii) The effective resistance of parallel combination is given by
