Simplest Possible Circuit

Simplest possible circuit The circuit elements are specified: the power supply or battery provides a stated emf and is connected across a resistance R. The emf of the battery is applied directly across the resistor; i.e. the voltage provided by the battery is identical to the voltage difference between points a and b. Thus by applying Ohm's law to the single resistor, connected to a single emf:
