... The diagram below shows how one type of fuel gauge in a car works. A sliding contact makes contact with a resistance wire wound in a coil (rheostat). It is connected to a float via a pivot P. When the petrol level changes the circuit resistance changes. This causes the pointer in the fuel gauge to m ...

... The two branch currents in the circuit are then 1 ampere and 2 amperes. The total current drawn from the battery is then 3 amperes. Just as in a circuit with only one resistance, any branch that has less resistance will draw more current. If R1 and R2 were equal however, the two branch currents woul ...
