Capacitance Flashcards
1
Q
What is a capacitor?
A
A device that stores energy and electrical charge.
2
Q
If there is a positive charge on one plate and a negative charge on the other, what is the voltage between these plates?
A
V
3
Q
When a capacitor is charges, is it negatively or positively charged? Explain why?
A
Both are wrong. It’s negatively charged because one plate is positively charged and the other is negatively charged.
4
Q
What is a dialetric?
A
An electrical insulator that can be polarized by an applied electric field.
5
Q
What is the difference between calculating the capacitance in series and in parallel?
A
Draw it on the page.
6
Q
