Series & parallel circuits Flashcards
1
Q
How do you calculate the resistance in a series circuit?
A
RT = R1 + R2 + R3 + R4 + ….
2
Q
What stays the same in a series circuit?
A
The current stays the same.
3
Q
What changes in a series circuit?
A
The voltage changes.
4
Q
What stays the same in a parallel circuit?
A
Voltage stays the same.
5
Q
What changes in a parallel circuit?
A
The current is divided between the circuits branches.
6
Q
How do you calculate total resistance in a parallel circuit?
A
Rt = R1xR2/R1+R2 then total then add the next resistor until Rt is met
7
Q
How do you calculate a missing resistor in a parallel circuit?
A
R2 = R? x Rt / R? - Rt
