Capacitive loads store electrical energy in a capacitor and release it back into the circuit. Unlike resistive loads or inductive loads, CLs have the characteristic of the current reaching its peak before the voltage does.
Since the capacitor blocks DC current and allows AC to pass through it, the capacitive load shows very high resistance for DC supply and low resistance for AC. Capacitive load can also store Electrical energy in the form of electric charge and return back to the source.
Capacitor banks are installed to improve the power factor of a load or system. Their job is to supply the reactive power. Therefore, we cannot call capacitor banks as capacitive load. Because, load is something that absorb the power.
Current is a good analogy to force as it is proportional to torque in motors. So Capacitive loading is like choosing bigger shocks for a heavier vehicle to create a greater force to slow down the axle over a bump. A washboard road creates an AC force on the axel and the shocks must be selected to match the spring-mass resonance for best damping.
Every capacitive load has some internal resistance. In capacitive load, Current leads voltage by 90 degrees. Hence it has a leading power factor. Since the capacitor blocks DC current and allows AC to pass through it, the capacitive load shows very high resistance for DC supply and low resistance for AC.
Current and voltage in a capacitive load are out of phase, just like in an inductive load. The distinction is that with a capacitive load, the current reaches its maximum value before the voltage rises. The current waveform precedes the voltage waveform, but with an inductive load, it lags behind.

What is capacitive loading? (Intuitive understanding)
A useful capacitive load is, for example, the capacitor in an RC integrating circuit. In this case, its slow charging is something we want, because it allows us to get an idea of the time through the voltage (hence the resistor in series to the capacitor). In this way, we can make timers (555), ramp generators and more.
