Q. 1 M ohm , 1 W resistance is likely to be a:

A
Wire wound resistor
B
Carbon resistor
C
Rheostat
D
None of the above.
Solution:

There are many types of resistors, both fixed and variable. The most common type for electronics use is the carbon resistor. They are made in different physical sizes with power dissipation limits commonly from 1 watt down to 1/8 watt. The resistance value and tolerance can be determined from the standard resistor color code.
