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
