[amp_mcq option1=”1 k ohm” option2=”100,000 ohm” option3=”one-millionth of an ohm” option4=”one million ohms E. None of the above” correct=”option4″]
The correct answer is D. 1 megohm is equivalent to one million ohms.
An ohm is a unit of electrical resistance. It is the resistance between two points in a conductor when a constant current of one ampere produces a potential difference of one volt between the points.
A megohm is a million ohms. It is a very large unit of resistance, and is often used to measure the resistance of insulators.
Option A is incorrect. 1 k ohm is equal to one thousand ohms.
Option B is incorrect. 100,000 ohm is equal to one hundred thousand ohms.
Option C is incorrect. One-millionth of an ohm is equal to one microhm.
Option E is incorrect. 1 megohm is equivalent to one million ohms.
