Voltage across components in a series circuit
The voltmeter is connected in parallel with the component. The supply voltage is shared between components in a series circuit, so the sum of the voltages across all of the components in a series ...

Calculating the value of the series resistor
A LED takes a current of \(12.5 mA\) when the voltage across it is 2 V. Draw a suitable circuit and calculate the value of the series resistor needed to operate the LED from a \(9 V\) battery.
