WASSCE Physics 2026 Question 10 — Lost Volts and Internal Resistance Explained

Can you identify where the lost volts of an electric cell occur? In this WASSCE Physics 2026 Question 10 explanation, we examine the meaning of lost volts and show why the correct answer is the internal resistance of the cell. Question: The lost volt of a cell is the potential difference across A. the terminals of the cell. B. an external resistor. C. the internal resistance of the cell. D. a voltmeter. Correct answer: C. the internal resistance of the cell. Key formula: Lost volts = Ir Where: I = current flowing through the cell r = internal resistance of the cell Ir = potential difference lost inside the cell We also use: V = E − Ir Where: V = terminal potential difference E = electromotive force Ir = lost volts Watch the full explanation to understand why the other options are incorrect and practise with solved examination-style questions.
