You're on a roll — Here are the solutions to question 11: a) Two factors that determine the sensitivity of a moving-coil galvanometer are: • The strength of the magnetic field in which the coil rotates. • The number of turns in the coil. b) (i) When more bulbs are added in series with the first one: • The total resistance of the circuit increases. • The brightness of each bulb decreases. (ii) (α) The circuit diagram for reducing the current passing through a galvanometer by means of a resistor in series is shown below: ` +---[ Resistor (R) ]---+ | | ---[ Galvanometer (
