Question

A photo-cell connected in an electrical circuit is placed at distance d from a source of light as a result current I flow in the circuit what will be the current in the circuit when the distance is increased to 2d,

Answer 1

Answer:

1/4

Explanation:

Intensity will be reduced as inversely proportion to distance

Answer 2

Explanation:

In photovoltaic cells, when light falls on the solar cells, the movement inside them produces small voltages that are scaled in eV or electronvolt. When the distance is increased from d to 2d than the intensity of light decrease by 2 folds, this ultimately decreases the voltage produced by the cells and this will also decrease the current in the circuit
