Solve problems involving electrical potential difference using 𝑉 = 𝑊 𝑞.

A student conducts two experiments to measure the potential difference across identical resistors in separate circuits. In experiment A, 450 J of energy is transferred when 30 C of charge passes through the resistor. In experiment B, 720 J of energy is transferred when 40 C of charge passes through the resistor. Compare the potential difference across the resistor in both experiments and identify which experiment demonstrates a higher rate of energy transfer per unit charge.

A charged particle with a charge of \(3.2 \times 10^{-19}\) C is moved through an electric field. The work done in moving the particle from point A to point B is \(9.6 \times 10^{-17}\) J. Calculate the potential difference between points A and B. Show your working.

A student measures the energy transferred to different charge carriers as they move through a component in a circuit. Refer to the table below. a) Deduce the potential difference across the component. b) Trial 5 involves a charge of 5.00 C. Predict the energy transferred in this trial and justify your prediction based on the trend in the data.
