SERIES AND
PARALLEL
HOW WE WIRE THE WORLD
Learning Objectives:
Know differences between series and parallel circuits.
Starter:
Match up the symbols with the words and pictures of
components.
• How many can you get right (we haven’t covered them all in class
yet!)?!?!
Series and parallel circuits
types of circuittypes of circuit
There are two types of electrical circuits;
SERIES CIRCUITS PARALLEL CIRCUITS
The components are connected end-to-end, one
after the other.
They make a simple loop for the current to flow
round.
If one bulb ‘blows’ it breaks the whole circuit
and all the bulbs go out.
The current has a choice of routes (paths).
The components are connected side by side.
If one bulb ‘blows’ there would still be a complete
circuit to the other bulb so it stays lit.
SERIES CIRCUIT PARALLEL
CIRCUIT
Wires need to be drawn
with a ruler and must not
cross each other.

  • 6. SERIES CIRCUIT PARALLEL CIRCUIT Wires need to be drawn with a ruler and must not cross each other.
  • 9. IES OR PARALLEL? 1.Would it be better to have the lights on a Christmas tree in series or parallel? Why? 2. Are the lights in your house connected up in series or parallel? How can you tell?
  • 10. SERIES VS PARALLEL CIRCUITS Series Circuit • Electrons only have one path to flow through. Parallel Circuit • There are MULTIPLE paths for the current to flow through.
  • 11. SERIES CIRCUIT• When electrons have to flow through one part to get to the next part • More components = more resistance • Increase resistance = decrease current (flow) • Less current = less bright bulbs • As voltage increases, current increases
  • 12. SERIES CIRCUIT – PROS & CONS Problems with Series: • The more devices (resistors) in a series circuit, the less current passes through (dimmer bulbs). • If one resistor breaks (a bulb goes out) the entire series is turned off.
  • 13. SERIES CIRCUIT - RESISTANCE • Resistors – resists the flow of electrical current • Increased resistance will reduce the rate at which charge flows (aka current) • Total resistance goes UP with each resistor since the current has must go through each resistor. • Total Resistance = Sum of all resistors in the series Req = R1+R2+ R3…
  • 14. SERIES CIRCUIT - CURRENT • Current = amount of charge (flow of electrons) • Like the flow of water • A current can't just disappear (appear) • Since only one path if some electrons flow through R1, then they have to continue flowing through R2 and R3. • Since the Current is the same through the entire circuit IT=I1=I2=I3
  • 15. SERIES CIRCUIT - VOLTAGE • Voltage is the electric equivalent of water pressure. • The higher the voltage, the faster electrons will flow through the conductor. • Each component has resistance that causes a drop in voltage (reduction in voltage). • Total Voltage = The sum of voltages across each series resistors VT = V1 + V2 + V3…
  • 16. SERIES VS PARALLEL CHART Series Parallel Voltage (V) Vtot = V1 + V2 + V3… Current (I) Itot=I1=I2=I3 Resistance (R) Req = R1+R2+ R3…
  • 17. Series Circuit - Example • Given – Vbattery = 12 V – R1 = 50 Ω, R2 = 100 Ω, R3 = 100 Ω • Complete the following table V = I R 1 2 3 ----------------------------------------------- T
  • 18. PARALLEL CIRCUIT – PROS AND CONS Advantages • The more devices (resistors) in a parallel circuit, does not decrease the current (does not dim bulbs). • If one resistor breaks (a bulb goes out) the rest do not. Problems • Current doesn’t stay the same for entire circuit • So energy is used up quicker • So the total current increases = faster electrons = hotter wire = fire?
  • 19. WHICH IS BETTER? SERIES OR PARALLEL? Parallel • Most things are wired in parallel • Because of the fact that the more you plug in, the intensity doesn’t decrease. • Of course, this also increases the risk of fire • This is why homes have fuses or circuit breakers. They turn off everything in the circuit when current moves too fast.
  • 20. TOLL BOOTH EXPLANATION•Adding toll booths in series increases resistance and slows the current flow. •Adding toll booths in parallel lowers resistance and increases the current flow.
  • 21. Parallel Circuit - Resistance • Resistors added side-by-side • The more paths, the less TOTAL resistance. 1/ Req=1/R1+1/R2+1/R3 • Ex. 2 resistors in parallel with 4Ω each. • Since the circuit offers two equal pathways for charge flow, only 1/2 the charge will choose to pass through a given branch.
  • 22. PARALLEL CIRCUIT - CURRENT • ALL paths are used! • But the charge divide s  up into all branches • One branch can have more current than another branch (depends on resistance in branch). • Total current = sum of current in each path IT = I1 + I2 + …
  • 23. Parallel Circuit - Voltage • A charge only passes through a single resistor. • Voltage drop across the resistor that it chooses to pass through must equal the voltage of the battery. • Total voltage = the voltage across each individual resistor VT = V1 = V2 = …
  • 24. SERIES VS PARALLEL CHART Series Parallel Voltage (V) Vtot = V1 + V2 + V3… Vtot = V1 = V2 = … Current (I) Itot=I1=I2=I3 Itot = I1 + I2 + … Resistance (R) Req = R1+R2+ R3… 1/Req=1/R1+1/R2+1/R3
  • 25. Parallel Circuit - Example • Given – Vbattery = 12 V – R1 = 50 Ω, R2 = 100 Ω, R3 = 100 Ω • Complete the following table: V = I R 1 2 3 ----------------------------------------------- T

  • 29. VOLTAGE, CURRENT, AND POWER• One Volt is a Joule per Coulomb (J/C) • One Amp of current is one Coulomb per second (6.24 x10^18 electrons/second). • If I have one volt (J/C) and one amp (C/s), then multiplying gives Joules per second (J/s) • this is power: J/s = Watts • So the formula for electrical power is just: • More work is done per unit time the higher the voltage and/or the higher the current P = VI: power = voltage × current
  • 30. TWO TYPES OF CURRENT •DC—Direct Current •produced by solar cells and chemical cells (batteries) •Current only flows in one direction. •AC—Alternating Current •Current flows back and forth (alternates) •Found in homes •Generators produce AC current

Editor's Notes

  1. That reduction in voltage is what is known as a voltage drop, and it comes about as the result of the work the battery has to do to illuminate the bulb. Each and every component in a circuit, including the wiring, offers a certain amount of resistance to the flow of electrical current and will cause an associated voltage drop.
