Matilda is working on a circuit project and needs to choose a capacitor to use as a bypass or reservoir. Which one of the following should she use:

• Electrolytic capacitor

• Tantalum capacitor

• Film capacitor

• Ceramic capacitor

Answer explanation

The answer is Electrolytic capacitor because

a) bypass circuits or reservoir circuits need to last longer as mucg as possible.

b) They have largest capacitance starting in uF while ceramic are usually measured in pF.
