Lab+6+Electricity

=﻿Materials= ==

=Exercise 1: Series Circuit= When I added the motor my lights went out but the motor kept running. This was due to too many resistors in my circuit. == == When I disconnected the item farthest from the circuit everything stopped working, due to the fact that the current was cut. All the electricity is on one circuit.
 * Key**

=2: Parallel Circuit= The parallel circuit makes the current stronger. Both my light and motor stayed on. == When I disconnected the light that was farthest away from the battery everything ran smoothly except for the piece that was disconnected.
 * Same Key as Single Circuit**

=Exercise 3: V/R=I=

I = current
====**﻿2)** RESISTANCE: Watts are a rating of "work" done by electricity. Discuss how much "work" it was for you to get the different bulbs to light? Click Here for a conversion chart.====

**watts = amps x volts**
The work or watts are dependent on the amount of voltage and amperage. Therefore in each trial there was a different amount of work because of the different variables.
 * Trial 1**
 * Voltage of battery || Amperage || Watts ||
 * 6 || 2 || 12 ||
 * 12 || 2 || 24 ||
 * 18 || 2 || 36 ||
 * 24 || 2 || 48 ||
 * Trial 2**
 * Voltage of battery || Amperage || Watts ||
 * 15 || 3 || 45 ||
 * 30 || 3 || 90 ||
 * 45 || 3 || 135 ||
 * 60 || 3 || 240 ||
 * Trial 3**
 * Voltage of battery || Amperage || Watts ||
 * 24 || 4 || 96 ||
 * 56 || 4 || 224 ||
 * 84 || 4 || 336 ||
 * 112 || 4 || 448 ||

Too many cords in one plug may cause a fire because it is too much current for the amount of space that all the energy running through.
 * 3)** Discuss the relationship between voltage, resistance, and amperage. Why are people always warned about plugging in to many items into a typical electrical extension cords?

Get a plug that is better capable of handling the current or amount of energy/voltage that the freezer needs.
 * 4)** You have a freezer too far away from the plug. You use a typical extension cord, but the cord feels warm or hot when the freezer is plugged in. Now what do you do?

How much resistance in needed to light the bulb in trial 1? How much resistance is needed to light a 3 amp bulb in trail 2? How much resistance is needed to light a 4 amp bulb in trail 3? Calculate the missing voltage/resistance form the table below. The light exploded because it was too much voltage for it. The light bulb would not turn on, in the real world it would most likely dim. When the light bulb is able to turn on without being dim or exploding. Has to the the perfect amount of light. One wasy is to use a cut potato to grab and pull the light bulb out.

 * If insufficient current reaches the light bulb?**
