Find currents in this electrical circuit.Watch
Hi, my task is to find the currents in each loop of the following circuit, using Kirchhoff's first law and Ohm's law.
I've decided to just apply Kirchhoff's law for each loop:
loop 1: 50(i1 - i2) + 30(i1 - i3) = 240V
loop 2: 50(i2 - i1) + 15i2 + 10(i2 - i3) + 25(i2 - i4) = 0V
loop 3: 30(i3 - i1) + 10(i3 - i2) + 20(i3 - i4) + 5i = 0V
loop 4: 25(i4 - i3) + (10 + 30 + 15)i4 + 20(i4 - i3) = 0V.
Are those equations correct? I don't want the answers to the equations, I just want to know if I've correctly formulated them.
