Question: What happens to the photoelectric current if the voltage across the electrodes is increased?

Options:

Correct Answer: Increases

Solution:

Increasing the voltage increases the photoelectric current by attracting more emitted electrons.

What happens to the photoelectric current if the voltage across the electrodes is increased?

What happens to the photoelectric current if the voltage across the electrodes is increased?

Step 1: Understand that the photoelectric effect involves light hitting a material and causing it to emit electrons.
Step 2: Know that these emitted electrons can create a current when they move towards an electrode.
Step 3: Recognize that voltage is like a push that helps move the electrons towards the electrode.
Step 4: When you increase the voltage, you provide a stronger push for the electrons.
Step 5: This stronger push means more electrons can reach the electrode, which increases the current.
Step 6: Therefore, increasing the voltage results in a higher photoelectric current.

Photoelectric Effect – The phenomenon where electrons are emitted from a material when it is exposed to light, and how the current is affected by voltage.
Electric Field Influence – Understanding how an increased electric field (voltage) can attract more emitted electrons, thus increasing current.
