1
Q
What is Kirchhoff’s second law?
A
Sum of EMF=Sum of PD around a closed loop
2
Q
Resistance equation in series circuits
A
R=R1+R2
3
Q
Resistance equation for parallel circuits
A
1/R=1/R1+1/R2
4
Q
What is lost volts?
A
EMF=terminal pd + lost volts
5
Q
Internal resistance equation
A
EMF=I(R+r)
6
Q
What are potential divider circuits?
A
The pd can vary across an output when connected to a fixed input
7
Q
Potential divider equation
A
V out=(R2/R1+R2)*V in
