Question

Calculate the current flows through the 10 Ω resistor in the following circuit.​

Answer 1

Answer:

First of all find out the equivalent resistance :-

let us consider now ,

• Resistance 1 ;R1 = 20Ω
• Resistance 2 ;R2 = 10Ω
• Resistance 3 ;R3 = 5Ω

To find out :- the current flows through the 10 Ω resistor in.

Calculation :-

We know that the arrangement of resistors are in parallel.

so, required formula

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

$\frac{1}{req}=\frac{1}{10}+\frac{1}{20}+ \frac{1}{5}$

But , all resistors are connected with parallel with 6volt battery .

In parallel combination current is different but the potential difference is same for each branch.

so,

$v = ir$

so,

$i = \frac{v}{r}$

$i = \frac{6}{10}$

$i = 0.6ampere$

Hence, the current flows through the 10Ω resistance is 0.6 A
