Question

the renistors are represented by light buibs, describe the change in a of the bulbs If R2 buns out when they are connected in series e brighine Enter the appropriate number in the cell. 1aBrigness increases 2 No change in brightnees 3 Brightness decreases 4-Lights go out 2-H inparallel circuit, what happens to the brightness if R1 burns out? Enter the appropriate number in the cell. 1 - Brigness increases 2 - No change in brightness 3 Brightness decreases 4 -Lights go out 3- Same as 2 above but R3 also burned out the cel. 1 Brigness increases 2 = No change in brightness 3 Brightness decreases 4 Lights go out 4 Given three different resistors, how many combinations are possible. List them below Enter the total number of combinations:

Explanation / Answer

1)when R2 burns out, circuit will be broken and the current will not flow.

So the correct option is lights go out.

2)

When R1 burns out, more current will flow through bulb and it will get brighter.

So the correct option is brightness increases.

3)

When R3 burns our, more current will flow through bulb and it will get brighter.

So the correct option is brightness increases.
