I was doing a Kirchhoff's Rules Problem and came up with the current equation I1=I2+I3 where I1=.153A, I2=.0675A, and I3=.0855A. The next question asks to calculate the power dissipated by the circuit. I am wondering what current I would use for the power equation, P=I^2R. Also would I have to figure out the resistance of the circuit?
