Question

A module with 40 cells has an idealized, rectangular I-V curve with I(sc) = 3.5A and V(oc)= 22.5 V. If a single cell has a parallel resistance of 4.5 Ω and negligible series resistance, draw the I-V curve if one cell is completely shaded. What current would the module deliver to a 12-V battery?
