DC Circuit Theory of Voltage, Current and Resistance
The relationship between Voltage, Current and Resistance forms the basis of Ohm''s law. In a linear circuit of fixed resistance, if we increase the voltage, the current goes up, and similarly, if we decrease the voltage, the current goes down. This means that if the voltage is high the current is high, and if the voltage is low the current is low.

When measuring the EMF of a battery and connecting the battery directly to a standard voltmeter, as shown in, the actual quantity measured is the terminal voltage V. Voltage is related to the EMF of the battery by V=emf−Ir, where I is the current that flows and r is the internal resistance of the battery.
A commonly encountered school-level Physics practical is the determination of the internal resistance of a battery - typically an AA or D cell. Typically this is based around a simple model of such a cell as a source emf in series with a small resistor. The cell is connected to a resistive load and (in the simplest case where load resistance …
