Question

The current through 1 `Omega` resistance in the following circuit is ______. 

Options

• 1.5 A

• 0.9 A

• 1.3 A

• 1.1 A

Answer 1

The current through 1 `Omega` resistance in the following circuit is 1.5 A. 

Explanation:

`"I"_1 xx 6 = "I"_2  xx 15`

`"I"_1 + "I"_2 = 2.1 `A

`"I"_1/"I"_2 = 15/6 `  `"I"_2/"I"_1 = 6/15`

`("I"_1 + "I"_2) /"I"_1= 21/15`

`therefore "I"_1 = 15/21 xx 2.1/10 = 1.5`A
