- Homework Statement:
- The symbol for photovoltaic cell is given below. The cell supplies current of magnitude ##I## at em.f. ##E##. Draw a diagram to show how two of these cells may be connected so that the combination supplies a total current greater than ##I## at the same e.m.f

- Relevant Equations:
- Series and Parallel

The answer from my teacher is two of these photovoltaic cells are connected in parallel. I can understand the parallel connection will produce same e.m.f but I don't understand why the total current will be greater than ##I##.

I imagined one of the cell connected to a lamp. The current through the lamp will be ##I##. And now there are two of these cells connected in parallel and I imagine a lamp also connected parallel to the two cells. The voltage on the lamp won't change so the current pssing thorugh it will also still be ##I##. What I think will change actually is the current provided by the cells, which is now becomes ##\frac I 2## but the total current would still be ##I##

Am I wrong? Thanks
