Answer:

1. When you plug in that second bulb, both will get equally dim, because you have added more resistance to your circuit, which decreases the flow of current. Adding another light bulb in series decreases the current because our battery now has more work to do!

2. When too much electricity flows through the filament, the filament overheats and melts, resulting in a gap. When bulbs have a melted filament, they have fused. Due to the gap in the filament, electricity is unable to flow through the filaments of fused bulbs, preventing them from lighting up.

1. If one bulb burns out in a series circuit, the entire circuit is broken. In parallel circuits, each light bulb has its own circuit, so all but one light could be burned out, and the last one will still function. ... Also, the brightness of the bulbs would be greater than the brightness of bulbs in series.

Advandages:

1. Every unit that is connected in a parallel circuit gets equal amount of voltage.

2. It becomes easy to connect or disconnect a new element without affecting the working of other elements.

3. If any fault happened to the circuit, then also the current is able to pass through the circuit through different paths.

Disadvantages: 1. It requires the use of lot of wires.

2. We cannot increase or multiply the voltage in a parallel circuit.

3. Parallel connection fails at the time when it is required to pass exactly same amount of current through the units.
