Which of the following statements explains lost volt in an electric circuit? The
total p.d from a source to maintain a flow of current through the circuit as well as the source
p.d to drive current through the circuit component except the source
p.d across all external components connected to the source of electricity
p.d across the internal resistance of the cell
Spiegazione
The lostvolt is the potential drop in a cell due to internal resistance.
