1. The problem statement, all variables and given/known data Please look at the attachment. 2. Relevant equations ΔV=I*R R=ΔV/I Power=I*ΔV 3. The attempt at a solution I said that ΔV of A and ΔV of B are the same (each 3/2 V). Using this, I got that the current at A = 3/20 Amps. However, this means that the current at B and C is each 3/40 Amps. However, then the 1.5 V * 3/40 does not equal 10 ohms, which is given. How am I supposed to go about this problem to find the power dissipated in each bulb and find what changes in terms of bulb brightnesses in A and B if bulb C is unscrewed?
