This is the introduction.

harge, and perform many other useful functions in circuits. The charge Q on a Capacitors store c capacitor's plates is proportional to the potential difference V across the capacitor. where C is a proportionality constant known as the capacitance. Capacitance has units of farads (F) (1 farad 1 coulomb/volt) If you imaging a charged up capacitor as being a bunch of electrons on a piece of metal, then you can further imagine that, if a wire is connected to the capacitor, these electrons will want to drain off of the capacitor - and what are moving electrons but current? The capacitor only has a finite capacity for charge, so the current will decrease with time. This charging/discharging will be the focus of this lab This process causes the potential across the capacitor to decrease exponentially with time as follow:s where Vo is the initial potential across the capacitor, t is time, R is the resistance in the circuit and C is the capacitance. The rate of the decrease is determined by the product RC, known as the time constant of the circuit. When the capacitor is charged, the potential across it approaches the final value Vo following the relation v(t) (1-e-t/RC) = As you can see, the same time constant RC describes the rate of charging as well as the rate of discharging

Explanation / Answer

As time constant = RC

=> C = time constant/R where R is the resistance of the circuit.

So for a higher value of C , time constant of circuit will be larger.
