Question

Study the following circuit and answer the questions that follows:

(a) State the type of combination of the two resistors in the circuit.

(b) How much current is flowing through

(i) 10 Ω and

(ii) 15 Ω resistor?

(c) What is the ammeter reading?

Answer 1

(a) Two resistors are in parallel combination.

(b) Current through

(i) 10 Ω → I = \(\frac { V }{ R }\) = \(\frac { 3 }{ 10 }\) = 0.3A

(ii) 15 Ω → I = \(\frac { V }{ R }\) = \(\frac { 3 }{ 15 }\) = 0.2A

(c) Ammeter reading = Total current flowing through the circuit 

= 0.5 A.
