2.Explain how the bulbs are connected in series and discuss the observation in series combination
Answers
Placing cells in series increases the voltage in the circuit by 1.5 V for each cell. Increasing the voltage increases the brightness of the bulb. When a bulb in a series circuit is unscrewed all bulbs in the circuit go out. Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs.
Answer:
by following steps
Explanation:
Aim:Study the series combination of electric bulbs.
Items needed:3 or mor bulbs,copper wires,dry cell.
Description:
1.Take three or more bulbs.
2.Take a copper wire.
3.The second terminal of the bulb is connected to the first terminal of the second bulb.
4.The second terminal of second bulb is connected to the first of the third bulb and so on.
5.In this way bulbs can be connected in series.
6.The first terminal of the first bulb and second terminal of the third are connected to an electric cell.
SEE THE DIAGRAM
Observation:
In the series connection of one bulb gets fused all other bulbs will stop glowing.
