1. Cause and Effect

2.  Light Bulb  Short Wire  Long Wire  Coiled Wire  3v Battery  1.5v Battery

3. ++ x2 = Dimly lit bulb

4. x2 Blown bulb ++ =

5. +++= Brightly lit bulb

6. Very dimly lit bulb ++ + =

7. + + =

8. This happened because the coiled wire took longer to transfer the electricity, whilst the long wire took a shorter amount of time to transfer the electricity to the light bulb. Now talking about the batteries the 1.5v has less amount of electricity and the 3v has more electricity in it that’s why when you put two 3v batteries on the electricity circuit the bulb blew up, if you put two 1.5v batteries on the electricity circuit it will just shine very brightly.
