In a series circuit, the current is constant throughout. However, electric bulbs and heaters require currents of widely different values to operate properly, making it impractical to connect them in series.
Why is it impractical to connect an electric bulb and an electric heater in a series circuit?

Connecting an electric bulb and an electric heater in a series circuit is impractical due to their different power requirements and characteristics. Electric bulbs typically have higher resistance and lower power consumption, while electric heaters have lower resistance and higher power demands. In a series circuit, the same current flows through all components, which would lead to inadequate brightness in the bulb and insufficient heating in the heater. A parallel circuit is more suitable for such devices, allowing independent operation with individual current paths, ensuring each device receives the necessary current for optimal performance without affecting the other’s functionality.
