Question

find the current is in the circuit ?
​

Answer 1

Answer:

i = 1.2 [amp]

Explanation:

In order to find the current in the circuit, we must perform a sum of voltages equal to zero, around the mesh.

∑V = 0

Let's take the direction of the current as shown in the drawing Clockwise.

$-3+(i*2)+(i*1)+(i*2)+9=0\\6+(5*i)=0\\5*i = - 6\\i = - 1.2[amp]$

Note: The negative sign means that the current moves in a counterclockwise direction.
