Q
- As you go across a circuit V=0
- One big loop
- Add smaller loops until every circuit element is touched
A
Kirchhoff’s Law
7
Q
- V-IR-IR=0 (Make this equation for each loop)
- If you go through a battery from – to +, then I add the voltage
- If the direction of the loop is in the same direction as the I then subtract IR
- Sum of I
- Substitution
A
Loop rules

Q
Capacitors block _ voltage.
A
DC
9
Q
Each _ has a charge and its equal and opposite.
A
Plate
10
Q
_ is how much charge you can store between the two plates.
A
Capacitance
11
Q
_ is a material placed in between the plates of a capacitor that increases the capacitance (usually an insulator between two metal plates) and atoms are polarized and they align.
A
Dielectric
12
Q
_ means dielectric.
A
Insulating

Q
When _ is open no more charge can move (Q is constant).
