Three resistors of 6 ohm, 2 ohm and 4 ohm respectively are joined together as shown in the figure. The resistors are connected to an ammeter and to a cell of e.m.f 6 V. Calculate:
i) the effective resistance of the circuit.

ii) the current drawn from the cell.

i) Resistors R₂ and R₃ are ins series.

Because, equivalent resistance, R = 2+4 = 6 which is parallel to R₁ = 6 ohm

$So comma space 1 over R equals 1 over 6 plus 1 over 6 equals 2 over 6 rightwards double arrow space space space space space R equals 3 capital omega$
ii) Let, V = IR

I = $V over R equals 6 over 3 space equals space 2 straight A$
