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
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

Would two protons repel or attract to each other?
Would an electron and a proton repel or attract to each other
Slay the Dragon!!!In a parallel circuit the battery has a
voltage of 5V. Both lamps have a resistance of 6 ohms. Solve for the total resistance and current.
YAYYYY Ye Answer is Right!!!!!!
