Current Voltage | MCQs

Explanation

In photovoltaic cells, the current increases with the intensity of incident light.

More light intensity means more photons, which release more electrons, generating higher current.

Explanation

• The relationship between current and potential difference (voltage) across a resistor is governed by Ohm's Law, which states that: I = V/R
• where I is the current, V is the voltage, and R is the resistance.
• This relationship is linear, meaning that if the voltage is reversed (i.e., the connections across the resistor are reversed), the current will also be reversed, but the graph will still be a straight line.
