FACTORS THAT AFFECT THE CHARGING TIME OF A CAPACITOR Increasing the value of the capacitor ______________ the time taken to charge. Decreasing the value of the capacitor ______________ the time taken to charge. Increasing the value of R decreases the ______________ in the circuit and hence the time taken to charge the capacitor ______________. Decreasing the value of R increases the _____________ in the circuit and hence the time taken to charge the capacitor _____________.

It consists of one long resistor (usually a wound wire) and a sliding contact. As the sliding contact C is moved up the potentiometer towards A the resistance between B and C __________________ and hence the voltage across B and C will _____________________ . At the same time, the resistance between A and C will __________________ and so hence the voltage across A and ____________________.
