Question

Three resistance 4ohm,6ohm, and 12ohm, are connected in parallel with source of 6volt. find the current flowing through the circuit.​

Answer 1

$\frac{1}{r} = \frac{1}{r1} + \frac{1}{r2} + \frac{1}{r3}$

$= \frac{1}{4} + \frac{1}{6} + \frac{1}{12}$

$= \frac{3 + 2 + 1}{12}$

$= \frac{6}{12}$

$r = \frac{12}{6}$

$= 2 \: ohm$

$v = ir$

$6 = i \times 2$

$i = \frac{6}{2}$

I = 3A
