Experiments Day 1 Resistors.

Electronic Technology Definition: The technology of using small amounts of electricity for controlling, detecting, collecting, storing, retrieving and processing information. Applications: Thermostat, metal detector, video recorder, computer, calculator, telephone, television, radio, pace maker, EKG, digital watch.

1.You will receive a kit of electronic parts. 2.Every day you receive your kit, TAKE INVENTORY. 3.Match all of the items in your kit with the inventory sheets in your kit. 4.Report any missing item to your teacher. 5.At the end of class, re-inventory your kit. Check around where you worked for any loose parts.

Voltage is the electrical force that moves electrons through a conductor. V I R

CURRENT is the quantity or flow rate of electrons moving past a point within one second. V I R

Resistance is the force that reduces or stops the flow of electrons. V I R

Solderless Circuit Boards – The Bread Board On each side of the the “ditch” all the holes on each row are connected. We use the bread board to construct electronic circuits that we want to test. Because we do not use solder, it is easy to make changes and adjustments This is the “ditch”. It separates the sides. The holes are connected by rows not columns.

Resistors have color bands on them Colors are called the “color code” 4 bands on each resistor Band 1 = 1 st Digit Band 2 = 2 nd Digit Band 3 = Multiplier. Band 4 = tolerance Gold = 5% Silver = 10%

For each lab, you will need to complete the following: 1.Write the name of experiment. 2.Write objectives for the experiment. 3.List all of the parts that are needed for the experiment. 4.Draw and label the schematic. 5.Construct the experiment. 6.Do the experiment. 7.In complete sentences explain what you learned.
