4.5 Parallel Circuits Flashcards
1
Q
What is the total current in a parallel circuit?
A
The sum of the current through the separate components
2
Q
What is the potential difference like across each component in a parallel circuit?
A
The potential difference across each component is the same
3
Q
How does the size of the resistance of component affect the current?
A
The bigger the resistance of a component the smaller the current that will pass through the component
4
Q
How do you calculate the current through a resistor in parallel circuit?
A
I = V / R
5
Q
What does adding more resistors in a parallel circuit do?
A
Decreases the total resistance
6
Q
What does I represent?
A
Current
7
Q
What does V represent?
A
Potential difference
8
Q
What does R represent?
A
Component resistance
