(a)[2]
Calculate the resistance of the thermistor when the p.d. across it is 7.0 V.
(b)[2]
In Table 9.1, place ticks in the boxes that show the effect on the resistances of the resistor and the thermistor when the p.d. across them rises from 0 to 7.0 V.
(c(i))[2]
Calculate the current drawn from the supply.
(c(ii))[2]
Calculate the energy transferred by the supply in 5.0 minutes.
