(a(i))[1]
The potential difference (p.d.) applied to the resistor is increased. Tick the box that shows the effect on the resistance of the resistor. Options: resistance increases; resistance is constant; resistance decreases.
(a(ii))[1]
The potential difference (p.d.) applied to the lamp is increased. Tick the box that shows the effect on the resistance of the lamp. Options: resistance increases; resistance is constant; resistance decreases.
(b)[2]
Calculate the resistance of the lamp.
(c)[2]
Calculate the current from the supply.
(d)[2]
Calculate the total p.d. across the lamp and the resistor.
