For the circuit shown below, find out the current flowing

Home » Electric Circuits » Electric circuits miscellaneous » Question

For the circuit shown below, find out the current flowing through the 2 Ω resistance. Also identify the changes to be made to double the current through the 2 Ω resistance.

1. (5A ; Put V_s = 20V)
2. (2A ; PutV_s = 8V)
3. (5A ; Put V_s = 10A)
4. (7A ; Put V_s = 12A)

Correct Option: B

By super position, only voltage source

i₁ =	4	= 2 amp
	2

only current source i₂ = 2 - I _SC = 2 – 2 = 0
&there; Total current, i = i₁ + i₂ = 2 amp
For current to double, Put V_in = 8V, as current source has no effect while connecting it across voltage source.

&there; i = i ₁ + i ₂ =	8	+ 0 = 4 amp
