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!!!!!!
