Make a circuit containing an ammeter, switch, cell and a bulb connected in series.Repeat the experiment by increasing the number of cells in series.(i) What change occurred in the ammeter reading when the number of cells was increased?(ii) What about the intensity of light from the bulb?(iii) How are the current and the intensity of light related to each other?(iv) What is the current in a conductor if 2 C charge flows in 10s? |

Answer» (i) Ammeter reading increases (ii) Intensity of light increases (iii) As current in circuit increases, intensity of light increases. (iv) \(\text{I}=\frac{Q}{t}=\frac{2c}{10s}=0.2C/s \) = 0.2 A |
