Question 1: Changing AC to DC is called what?

Answer:

Rectification Question 2: A 5,000 BTU air conditioner can efficiently cool up to 150 square feet, or a 10-foot x 15-foot room. What does BTU stand for?

Answer:

British thermal unit

Question 3: A number-12 wire, compared to a number-6 wire is what?

Answer:

Is smaller in diameter Question 4: What will happen if you operate an incandescent light bulb at less than its rated voltage?

Answer:

The bulb will burn dimmer and last longer Question 5: Made from a variety of materials, such as carbon, this inhibits the flow of current.

Answer:

Resistor

Question 6: A resistor's first three color bands are brown, black, and red. What is its value?

Answer:

1,000 ohms Question 7: This is a type of semiconductor that only allows current to flow in one direction. It is usually used to rectify AC signals (conversion to DC).

Answer:

Diode

Question 8: Radar can operate at frequencies as high as what?

Answer:

100,000 MHz

Question 9: What do AC and DC stand for in the electrical field?

Answer:

Alternating current and direct current

Question 10: How are neutral wires always colored?

Answer:

Whitish or natural Question 11: In the U.S., all metal equipment, electrical or not, connected to a swimming pool must be what?

Answer:

Bonded together

Question 12: What does one use to measure electrical power?

Answer:

Wattmeter Question 13: A fuse with a higher-than-required rating used in an electrical circuit does what?

Answer:

May not work properly; Because fuses are designed to prevent current overload at a specific level, a fuse with a high rating may allow a higher current to flow through a circuit not designed to work at that level

Question 14: Ohm's Law states what?

Answer:

Voltage = Current x Resistance Question 15: A light bulb is 60 watts. Operated at 120 volts, how much current does it draw?

Answer:

0.5 ampere; Power = Current × Voltage or, written another way, Current = Power/Voltage. 60 watts / 120 volts = 0.5 amperes.

Question 16: Which one of the following is an active element?

Answer:

10 V power supply; Active elements are electronic devices that can create energy (such as voltage supplies and current supplies). Passive elements are electronic devices that cannot create energy.

Question 17: Voltage can also be expressed as what?

Answer:

Electrical potential difference Question 18: What do you call the removable memory card contained in new cell phones?

Answer:

A SIM card Question 19: A device that transforms energy from one form to another is called a what?

Answer:

A transducer

Question 20: Which is the most correct definition of current?

Answer:

The presence of electron flow
