Question 1: Most widely used general purpose resistor is the?

Answer:

Carbon resistor

Question 2: Potentiometers are made of?

Answer:

Carbon composition material formed in a broken cirle. The max ohm value is printed on the case. It has three leads are are configured to operateas a voltage divider controlling voltage by varying the circuit's resistance

Question 3: What type of resistors are even less likely to be damaged by heat?

Answer:

Wire wound resistors

Question 4: The fourth color band represents?

Answer:

The tolerance

Question 5: If a 2000 ohm resistor has tolerance of 10% what is the actual value?

Answer:

Anywhere between 1800 and 2200 ohms. 2000 x 10%=200 200-200=1800 2000+200=2200

Question 6: The second color band represents?

Answer:

The second number in the resistance value

Question 7: Potentiometers are used when?

Answer:

Circuit current flow is low.

Question 8: Fixed resistors are classified in what three categories?

Answer:

General purpose, Power, Precision

Question 9: What is this sybmol ??

Answer:

Is the Greek letter omega that abbreviates ohm. 10 ohms= 10 ?.

Question 10: These codes are called military specification codes.

Answer:

CGW RN65D 3572FJ

Question 11: What does W stand for?

Answer:

Wire Wound

Question 12: "WINS" Color White represents?

Answer:

Significant number 9 Multiplier 1,000,000,000

Question 13: The value of resistance is normally?

Answer:

Printed on the body of the resisor and followed by a ? symbol, a k or an M.

Question 14: What are the two types of variable resistors?

Answer:

Potentiometers and Rheostats

Question 15: What does the N in CGW RN65D 3572FJ mean?

Answer:

The second letter is the style. N- Metal Film, W- Wire Wound, CR- Carbon

Question 16: Carbon based resistors are used when?

Answer:

Circuits that only require the accuracy to be within 5%

Question 17: Insulators are considered to have ---to current flow?

Answer:

Maximum resistance

Question 18: Power resistors are normally made of?

Answer:

Wire wound around a core. They may be called wire wound resistors

Question 19: What is the letter J in CGW RN65D 3572FJ represent?

Answer:

J is used for special purposes. In this case means this resistor meets military specifications

Question 20: Rheostats are used when?

Answer:

With higher levels of current

Question 21: As tolerance decreases, the amount of the difference?

Answer:

Decreases Question 22: What resistor is not as likely to be damaged by heat as a carbon composition resistor?

Answer:

Carbon film resistors

Question 23: Rheostats are made of?

Answer:

Wire wound on a core in a broken circle. Its max ohm value is printed on the case They have two leads and are configured in a circuit to control current

Question 24: "YOUNG" Color Yellow represents?

Answer:

Significant number 4 Multiplier 10,000

Question 25: Carbon film resistors are smaller than?

Answer:

Carbon composition resistors

Question 26: The higher the ohmic value?

Answer:

The highter the resistance The less current flows
