Question

calculate the value of current in given circuit?​

Answer 1

Answer:

equivalent resistance=10ohm

current=15/10=1.5A

Explanation:

current will pass through the part where resistance is not present between the+ve&-ve terminals. so first resistor & last resistor only should be taken.

Answer 2

Answer:

According to Ohm's Law, V = IR.

In the given circuit, V = 15V.

R in outermost circuit,

It is connected in parallel

1/R = 1/R₁ + 1/R₂

1/R = 1/5 + 1/10

R = 10/3Ω

In second last circuit, it is connected in parallel.

1/R₁ + 1/R₂ = 1/R

1/R = 1/15 + 10/3

R = 15/51Ω

V = IR

--> I = V/R

--> I = 15/(15/51)

--> I = 15 * 51/15

--> I = 51A
