R circuit (pretty simple) need checked - full working - please!!! 1. The problem statement, all variables and given/known data see attachment 2. Relevant equations P=IV P_loss=I^2 R V=IR 3. The attempt at a solution ok 36=I^2*12 I_12Ω=√3 A V=20.8V That is the same for the 3 resistors in parallel (I hope) so I18Ω=1.15A I36Ω=0.577A the sum of these will give me the current through the unknown resistor Iunknown=3.46A net voltage = 60 60=Vunknown + 20.8 Vunknown=39.2V V=IR R=11.3Ω can someone please check this - wouldn't ask if I dint need it.
