Question

Two electronics technicians are looking at the technical manual for a piece of electronic equipment. The manual refers to a particular resistor as a "2.2 megohm resistor." Technician A says that this means that the resistance value of the resistor is 22,000 ohms. Technician B says that this means that the resistor can safely carry a current of 2,200,000 amperes. Which of the following statements is correct?

A. Only Technician A is correct.
B. Only Technician B is correct.
C. Both Technician A and Technician B are correct.
D. Neither of the two technicians is correct.

Answer 1

Technician A is incorrect because '2.2 megohm' refers to 2.2 million ohms. Technician B is incorrect because resistance value does not determine current carrying capacity.

Step-by-step explanation:

The correct statement is that Neither of the two technicians is correct.

Technician A is incorrect because the term '2.2 megohm' refers to a resistance value of 2.2 million ohms, not 22,000 ohms. The prefix 'mega-' represents a multiplier of 10^6.

Technician B is incorrect because the resistance value of a resistor does not determine the current it can safely carry. The current carrying capacity depends on factors such as the power rating and heat dissipation of the resistor.
