(a) Labelled diagram of the arrangement is shown below:

Two resistors of resistance 4 Ω and 6 Ω are connected in parallel to a cell to draw 0.5 A current from the cell. Draw a labelled diagram of the arrangement. Calculate the current in each resistor. Current Electricity, Concise Physics Solutions ICSE Class 10.

(b) Two resistors of 4 Ω and 6 Ω are connected in parallel. If the equivalent resistance of this part is R_p then Hence, equivalent resistance = 2.4 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 2.4 = 1.2 V Current through 4 Ω = ? From Ohm's law V = IR Substituting the values in the formula above, we get, 1.2 = I x 4 I = 1.2 / 4 = 0.3 A Hence, current through 4 Ω resistor = 0.3 A Current through 6 Ω = ? From Ohm's law V = IR Substituting the values in the formula above, we get, 1.2 = I x 6 I = 1.2 / 6 = 0.2 A Hence, current through 6 Ω resistor = 0.2 A
