Question

a person connects a bulb having resistance and an electric heater having resistance in series but they do not work properly when he connects the same appliances in parallel in the circuit their function normally explain the reason for this​

Answer 1

in series current flows equally in circuit while in parallel current has to option so, current in that direction where resistance is less.. hence, u connect in parallel most of current towards the bulb as it offer less resistance in compare to heater due to which heater is unable to function properly.
