Dear Student

So here we can see that power in parallel circuit is more than series circuit. So bulbs connected in parallel will grow more.

b) If one of the bulb got fused then in series circuit, circuit wil break and hence no other bulb will glow.
In parallel circuit only that branch will be out of circuit and hence other bulbs will glow.

c) Circuit diagrams as shown above.
