A potential difference (p.d.) across a resistor causes a current in it. The p.d. and the resistance of the resistor can both be changed. Which row shows two changes that will both decrease the current in the resistor?
decrease p.d. and decrease resistance
decrease p.d. and increase resistance
increase p.d. and decrease resistance
increase p.d. and increase resistance
