Question

there are 3 resistors 15 ohm, 20 ohm and 10 ohm are connected in parallel with 6 volt battery find the current passing th​

Answer 1

Answer:

1.3 Amperes

Explanation:

$\frac{1}{R_{eq} } = \frac{1}{R_{1} } + \frac{1}{R_{2} } + \frac{1}{R_{3} }$

⇒ $\frac{1}{R_{eq} } = \frac{1}{15} + \frac{1}{20} + \frac{1}{10}$

LCM of 15, 20 and 10 is 60.

$\frac{1}{R_{eq} } = \frac{4 + 3 + 6}{60 }$

∴ $R_{eq}$ = $\frac{60}{13}$

V = 6 V [Given]

As V = I·R

⇒ I = V/R

⇒ I = 6/(60/13)

⇒ I = (6/60) · 13

∴ I = 13/10 Amp

Or I = 1.3 Amperes
