When I was reading about capacitance in the AQA textbook in which there was a circuit given with the components of a switch , a capacitor , a variable resistor , ammeter in series and voltmeter in parallel across the capacitor.

When observing the relationship between Charge and Potential difference when current was constant ,[ I couldn't understand why the Potential difference was increasing while the charge was increasing for the capacitor.]

Is it alright if someone could explain why the potential difference increases while charge increases at a constant current?

It's mainly to do with the capacitance equation Q=CV (or C=Q/V if you prefer it that way). The capacitance of any component is fixed therefore as if Charge (Q) increases then voltage must also increase by the same amount in order to maintain the same capacitance.
