(a) Define a series electric circuit.
(b) A torch has three identical cells connected so that the current has only one path to follow. Explain, without using calculations, why the current is the same through every cell and the filament of the bulb.
(c) The same torch is fitted with three resistors of different values connected in series across a battery. Describe qualitatively how the potential difference of the battery is shared among the three resistors.
b. (b) Explain, without calculations, why the current is the same through every component when several are connected in series.
c. (c) Describe qualitatively how the potential difference of the source is divided among three unequal resistors connected in series.
