KVL: At any instant in a closed loop the algebraic sum of the e.m.f's acting round the loop is equal to the algebraic sum of the p.d's round the loop.
The Attempt at a Solution
R1 = BROWN, RED, BLACK, NONE
R2 = BROWN, GREY, BROWN, SILVER
R3 = ORANGE, WHITE, BROWN, GOLD
R4 = BROWN, BLACK, RED, SILVER
R5 = BROWN. RED, RED, RED
I want to add R2 and R4 because they are in series. 180ohms + 1000ohms = 1180ohms
The R2+R4 are in parallel with R5. (1/1180+1/1200)^-1=594.96ohms
Okay so I'm pretty sure this is not correct but the middle area with R2, R4 and R5 is really confusing me.
Why is there I5 when we already have current I2?
Also I assume I4 is the little arrow indicated above R4 but by that reasoning then there should be a current above R2 as well?
Please help me understand this.
