HOMEWORK QUESTION 1:
Can you name three (3) different types of capacitors?
A little confused here, so it will tell you what a search revealed: Ceramic, Electrolytic, and Tantalum (some good reading out there on a search, lots of interesting tangents :mrgreen: ).
HOMEWORK QUESTION 2
What ‘Units’ are used to describe a capacitor’s capacitance?
Farad
HOMEWORK QUESTION 3
Convert the value of 2.2µF (micro-Farad) into pF (pico-Farad), mF (milli-Farad) and F (Farad).
2,200,000,000pF, .0022mF, .0000022F
HOMEWORK QUESTION 4
Can a 0.1µF capacitor store more charge than a 1 mF capacitor?
1uF=.001mF therefore .1uF=.0001mF, so the 1mF can store 10,000x more than the .1uF.

Good answers Shawn!

Only 1 issue on problem 3:

2.2µF = 2,200 nanoFarad = 2,200,000 picoFarad

Can you name three (3) different types of capacitors?
Dielettric capacitors, ceramic capacitors, film capacitors.

What ‘Units’ are used to describe a capacitor’s capacitance?
Farad (F).

Convert the value of 2.2µF (micro-Farad) into pF (pico-Farad), mF (milli-Farad) and F (Farad)
2.2uF= 2.2*10^6pF=2.2*10^-3mF=2.2*10^-6F

Can a 0.1µF capacitor store more charge than a 1 mF capacitor?
No, because 0.1uF is minor than 1mF.
