I have attached the circuit of interest. The 2 resistors of of resistance R. V1 and V2 are the voltage sources. 'I' is the current we're solving for. Using KVL, we get: -V1-R*I+V2-R*I=0 Rearranging: V1-V2=-2R*I (V2-V1)/(2R)=I My answer doesn't seem to match the solutions. Am I missing something here?
