Question

What is the difference in brightness of bulb in series and parellel

Answer 1

In series circuit , the amount of current in the circuit decreases and become low in the last resistance .
On the other hand , in parallel circuit, the amount of current remains same in all the resistances.
So, the brightness of a bulb will be low in series circuit and high in parallel circuit
Hence, the parallel circuit is more advantageous than the series circuit

Series circuit

→ The current in each resistor have the same value.

→ The total voltage drop is equal to the supply voltage.

→ The effective resistance is always more than the minimum value resistance in the series circuit.

_________________________

Parallel circuit

→ The voltage across each resistor is equal to the supply voltage.

→ The total current in the circuit is equal to the sum of the current in individual parallel circuit.

→ The effective resistance is always less than the minimum value resistance in the parallel circuit.
