KnowledgeBoat · Accepted Answer

(a) Labelled diagram of the arrangement is shown below: (b) Two resistors of 2 Ω and 3 Ω are connected in parallel. If the equivalent resistance of this part is R_p then Hence, equivalent resistance = 1.2 Ω Current I = 0.5 A Potential Difference V = ? From Ohm's law V = IR Substituting the values in the formula above, we get, V = 0.5 x 1.2 = 0.6 V Current through 2 Ω = ? From Ohm's law V = IR Substituting the values in the formula above, we get, 0.6 = I x 2 I = 0.6 / 2 = 0.3 A Hence, current through 2 Ω resistor = 0.3 A Current through 3 Ω = ? From Ohm's law V = IR Substituting the values in the formula above, we get, 0.6 = I x 3 I = 0.6 / 3 = 0.2 A Hence, current through 3 Ω resistor = 0.2 A
