IF temperature of circuit increases , what will be the result for current and potential difference? current increase and potential dfference decreases. i don't understand why the pd decreases?

The current should decrease due to more vibrating latttice ions which offer more resistance to current flow NO?

I'm pretty certain thats wrong unless their is an ntc resistor in your circuit?

If the temperature of a circuit increases for a component, there will be more collisions between lattice ions and charge carriers (electrons) thus resulting in a higher resistance. Not sure where this question is from but it seems incorrect. Potential difference must increase in order for the current to increase for a higher resistance. But for more current to a flow a higher PD is needed so as R increases, so does I and so does V. We use V=IR to determine what increases and decreases.
Unless the question is about a thermistor. In which case as temperature increases, resistance decreases which means you need less PD for a fixed current. << This would make sense for your question
