What does the term 'lost volts' refer to in a circuit?.
- A.The voltage drop across the internal resistance of a cell
- B.The total voltage supplied by the cell
- C.The voltage at the terminals of the cell
- D.The voltage used by external components
Model answer
What a good answer should say
- The voltage drop across the internal resistance of a cell
Explanation
Why this works
Lost volts refer to the voltage that is lost due to the internal resistance of the cell when current flows. This concept is crucial for understanding the efficiency of power sources.
