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 reisitance 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 B is correct
d. neither of the two technicians is correct

D.
2.2 Megohms is 2,200,000 Ohms. The resistance in Ohms of a resistor does not indicate the current rating of a resistor. The power rating (measured in Watts) determines how much current the resistor can handle.

d. neither of the two technicians is correct
2.2 Mega ohms = 2.2 * 10 ^ 6 = 22,00,000 ohms.
in reality 2200, 000 Amperes is too much and i doubt whether even a lightning can generate that much of a current.
