Question
Draw neat and labelled diagram.
One solar panel produces a potential difference of 18 V and current of 3 A. Describe how you can obtain a potential difference of 72 Volts and current of 9 A with a solar array using solar panels. You can use sign of a battery for a solar panel.

Solution
Given a potential difference of 18 V and a current of 3 A, the required output is a potential difference of 72 V and a current of 9 A. In a circuit, voltage stays the same when components are connected in parallel, but it increases when they are connected in series. On the other hand, current remains unchanged in a series connection, while it increases when components are connected in parallel.
