Draw a schematic diagram of a circuit consisting of a battery of three cells of 2 V each, a 5 \(\ohm\) resistor, an 8 \(\ohm\) resistor, and a 12 \(\ohm\) resistor, and a plug key, all connected in series.
Draw a schematic diagram of a circuit consisting of a battery of three cells of 2 V each, a 5 \(\ohm\) resistor, an 8 \(\ohm\) resistor, and a 12 \(\ohm\) resistor, and a plug key, all connected in series.

A battery with three 2 V cells equals a battery with a potential of 6 V. Three resistors with resistances of 12 ohms, 8 ohms, and 5 ohms are connected in series with a battery with a potential of 6 volts in the circuit diagram below.
