Technician: Circuit Types

Series Circuit

In which type of circuit is current the same through all components? A. SeriesB. ParallelC. ResonantD. Branch The answer here is A. Series.  The reason why is pretty straight forward.  If you line up a series (ha!) of components in a straight line, the output of each going into the input of the next, then …

Technician: Amplifier Components

Amplifier Components

Which of the following electronic components can amplify signals? [T6B05] A. Transistor B. Variable resistor C. Electrolytic capacitor D. Multi-cell battery The answer is, as luck would have it, A. Transistor.  The transistor is probably the miracle of 20th century technology.  It’s an amplifier, a switch, and so much more. None of the other components …

Technician: Electric Field

Capacitance Meter

What is the ability to store energy in an electric field called? [T5C01] A. Inductance B. Resistance C. Tolerance D. Capacitance Hate to say it, but this is basically a definition question.  The answer is D. Capacitance.  The easy way to remember this is just think about capacitors, the devices that actually store the electric …

Technician: Ammeter Current Display

Ammeter Current Display

If an ammeter calibrated in amperes is used to measure a 3000-milliampere current, what reading would it show? [T5B06] A. 0.003 amperes B. 0.3 amperes C. 3 amperes D. 3,000,000 amperes Don’t panic! This is a simple question about unit conversions, nothing more. Remember your definitions of metric prefixes.  Milli means one one-thousandth, or 0.001.  …
