Question

Find the equivalent resistance of the circuit shown in the figure. Assume that V = 24.5 V, R1 = 18.6 Ω, R2 = 9.42 Ω, R3 = 6.19 Ω and R4 = 16.8 Ω.

Answer 1

R1,R2,R3 are in parallel combination

$\frac{1}{R_{123}} = \frac{1}{18.6}+\frac{1}{9.42}+\frac{1}{6.19}$

$\frac{1}{R_{123}} = 0.321$

${R_{123}} = \frac{1}{0.321}$

${R_{123}} = 3.11\Omega$

$R_{net} = 3.11+16.8 = 19.91\Omega$
