A portable solar charger containing multiple solar cells is used by campers to charge their devices.
State the energy transfer taking place in the solar cells.
The solar panels generate a constant current of 1.8 A. State the equation linking charge, current, and time.
Calculate the charge transferred by the solar cells in 40 seconds40\text{ seconds}40 seconds.
The individual solar cells in the charger are connected in parallel. Suggest why they are connected in parallel rather than in series.
