Three resistors having resistance r_{1}, r_{2}, and r_{3} are connected as shown in the given circuit. The ratio i_{3} / i_{1} of currents in terms of resistances used in the circuit is:

Solution & Step-by-step Explanation

Current i_{1} enters the parallel combination of r_{2} and r_{3} .According to the current division rule: i_{3} = i_{1} \times \frac{r _{2}}{r _{2} + r _{3}} \frac{i _{3}}{i _{1}} = \frac{r _{2}}{r _{2} + r _{3}}

Try it yourself before checking the explanation above.

Three resistors having resistance r_{1}, r_{2}, and r_{3} are connected as shown in the given circuit. The ratio i_{3} / i_{1} of currents in terms of resistances used in the circuit is:

\frac{r _{1}}{r _{1} + r _{2}}

\frac{r _{2}}{r _{1} + r _{3}}

\frac{r _{1}}{r _{2} + r _{3}}

\frac{r _{2}}{r _{2} + r _{3}}
