Draw a schematic of an closed series circuit with one light and one fan. Make your power source be a compound battery in series.
List all the materials in the schematic
2 light bulbs 1 ammeter 1 switch 1 battery 6 wires
Draw a new schematic to show how you would connect a voltmeter and an ammeter to the circuit right:
Label the symbols
Label the symbols
L1
L3
OFF (this is not a circuit)
Because the volt meter needs to be set across the device it is measuring.
How many batteries are in the compound battery?
4 batteries
Draw a compound battery in parallel
Fig. 2 and Fig 1 are equal
Figure 1 will last longer
What are the advantages of a compound battery in parallel?
Compound batteries in parallel will last longer.
What are the advantages of a compound battery in series?
Compound batteries in series will provide more power (the fan will spin faster and the light will be brighter).
Which schematic(s) is a series circuit with a compound battery
Which schematic(s) is a s parallel circuit with a compound battery in series?
Which schematic(s) is is a parallel circuit
What is the units for electrical power?
Watts
What is the power rating if you have a 25 Amp saw that runs on 120 volt service ?
The power rating would be 3000 watts
A1=A2+A3 100=A2+50 A2=50
0.1A * 4V= 0.4 watts
Final Jeopardy Build a circuit
Final Jeopardy Directions: Draw a circuit with two batteries, three light bulbs, and two switches so that it has all the following components: A master switch that turns the entire circuit on or off Two light bulbs remain lit when the third light bulb is taken out of its light socket A switch that will turn two light bulbs on or off at the same time, but will keep the third light on
