Two lamps connected in series with an open switch and a cell The circuit diagram shows a circuit with two lamps connected in series. If one lamp breaks, the other lamp will not light. The current is ...

The two resistors have the same current through them. The potential difference across them will be different if they have different resistances. The total resistance (\(R_{T}\)) for this circuit is ...
