The DS-100 DC Circuits and the use of Meters Certification book contains a 50 question Multiple Choice Quiz which is used to gauge comprehension of the material that has been presented. To receive the certificate 80% comprehension is required.

The student must be well versed in the use of a Digital Multimeter to measure Voltage, Current and Resistance. The student must be able to determine:

If the Current is Amps, Milliamps, or Microamps.

If the Voltage is Kilovolts, Volts, Millivolts, or Microvolts.
If the resistance is Mega Ohms, Kilo Ohms, or Ohms.
Must be able to determine if the resistor is in tolerance. Determine the Maximum and the minimum value of resistance the resistor can have and still be good.
Given the value of the resistance determine the total resistance in a circuit that is connected in series, parallel or series parallel.
Given the value of the resistance determine the total current and the voltage across each resistor.

The DS-100 DC Circuits and the use of Meters Certification book also contains information on diodes and transistors, the 555 Timer and waveform generation using the 555 Timer.

**We hope to accomplish two objectives:**

**1.** If you are going to become a technician in either of these fields (Automotive Technician, Electronic Technician, Electrician, Mobile Technician, Solar Technician.) you will have a good foundation in the basics of electronics. You will feel confident that you will be able to perform at the entry level of an apprentice in regard to the electrical requirements of the field. You will feel confident that you are prepared to learn more from the company that you are working for and will benefit from more instruction on the job.

**2.** If you are investigating and trying to determine which direction you want to go that is do you want to become an Engineer? Do you enjoy solving electrical problems? Do you enjoy problem solving period? Do you appreciate the structure the circuit demands in order to find out how it will perform? For instance the formula for the Total Resistance of resistors connected in series is :

Rt = R1 + R2 + R3
