1. The problem statement, all variables and given/known data 1. 3 light bulbs are connected parallel in the circuit ,one of them burns out .How this affects the other bulbs. 2. We have combination of parallel and series circuit(3 bulbs) and one of them R3 burns out . This gives us a series circuit with 2 bulbs .What happens to the light?-----R3------ ---R1 ------R2----- 2. Relevant equations 3. The attempt at a solution 1.I know that in parallel circuit V1=V2=V3.If one bulb burns out the rest will stay on,but I'm not sure if the brightnes will stay the same. 2.For series circuit I1=I2,current will be the same,voltage will be different.What happens with the light ,is R1( one what was not in the parallel circuit )brighter?Please help me to understand this because I'm getting confused.
