(C)COULOM
B
Q
Current The flow of electrons from negative (-) to
positive (+) over time
Flow of Water through a pipe
I=Q/TCurrent =charge
divided by the time
Amperes(Amps)
I
Resistance
The slowing down of electrons in a current
Clog of a pipe ____________________ OHMSΩ
R
Voltage Measure of actual flow created
Water Pressure V=IR(Coulomb’s Law)
voltage = the current multiplied by the resistance
VOLTS V
An Ammeter : Measures Amperes
Battery: Source of energy
Resistor: removes energy
Voltmeter: Measures Energy

Series Circuits
In a series circuit : Voltage is distributed among the resistors:
Energy=V¹+V²+V³ The total resistance can be found by adding all of the
resistances: R= R¹+R²+R³
![Page 5: Sir Kit’s Great Adventure BY:MARISSA BENAVIDES & BROOKE MOLINA](https://reader035.vdocuments.us/reader035/viewer/2022062518/56649e5c5503460f94b53e5a/html5/thumbnails/5.jpg)
Finding Voltage, Current and Resistance for a Series Circuit
1) Find the total Energy (Volts from battery)
2) Find the total resistance
Total R=r¹ +r² +r³
3) Determine the total current
I = V/R
4)Because current is always constant in a series circuit , you can find the voltage by each resistor.
4V

In Parallel Circuits…..
Voltage is always constant

How to find V, I and R in a parallel circuit
1.Determine the total energy2.Find the total Resistance :
1/total R = 1/R¹ + 1/R² + 1/R³3.Find out the total current
leaving the energy source: Total Energy: Voltage/Resistance
