OCR A Physics A-Level PAG 3
prevent the internal resistance of the battery or cell from changing during the experiment. Use fairly new batteries/cells because the emf and internal resistance of run down batteries can …
Intro Lab
Since an ammeter has very little resistance, it will act as a short circuit if placed in parallel (across the terminals of) a substantial voltage source. If this is done, a surge in current will result, as shown in Figure 2, potentially damaging the …
Internal Resistance of a Battery
Batteries have internal resistance that depends on the size, chemical properties, age, temperature and the current of the battery. When the battery is connected to components in a circuit, the …
