Current Electricity: NEET 2021

Easy· Combination of resistors (Voltage Division and Current Division Rule)· +4 / −1

Three resistors having resistances

r_1

,

r_2

and

r_3

are connected as shown in the given circuit. The ratio

\dfrac{i_3}{i_1}

of currents in terms of resistances used in the circuit is : Figure: the current

i_1

enters at A and passes through

r_1

. It then divides into two parallel branches,

i_2

through

r_2

and

i_3

through

r_3

, which rejoin before reaching B. Question diagram
