Solution
The devices need to be linked simultaneously. The current flows continuously through the whole electric circuit in a series circuit. Consequently, it is plainly impractical to link an electric heater and light in series since they require currents with quite different values to function. Second, another significant drawback of a series circuit is that when one component fails, the entire circuit is destroyed, A parallel circuit, on the other hand, splits the current among the electrical devices. Thirdly, a parallel circuit has less overall resistance. This is helpful particularly when each gadget has different resistance and requires different current to operate properly.
