Question

What potential difference must be applied to the circuit if it

takes 40 Joules of energy to move12.48N X 10¹⁸ electrons?

Answer 1

To calculate the potential difference required to move a certain number of electrons, we can use the formula: Energy (J) = q (C) × V (V). Plugging in the given values, we can calculate the potential difference in Volts.

Step-by-step explanation:

To calculate the potential difference required to move a certain number of electrons, we can use the formula:

Energy (J) = q (C) × V (V)

Where:

• Energy is given as 40 Joules
• Charge (q) is given as 12.48N X 10¹⁸ electrons

We can rearrange the formula to solve for potential difference (V):

V = Energy (J) / Charge (q)

Plugging in the values, we have:

V = 40 J / (12.48N X 10¹⁸ electrons)

Simplifying the calculation gives us the potential difference required in Volts.
