Frequently Asked Questions
-
What does one megohm represent?
-
One megohm equals one million ohms and measures how strongly a material resists electric current flow.
-
Is volt per ampere the same as ohm?
-
Yes, volt per ampere (V/A) is the SI derived unit of electrical resistance and is equivalent to one ohm.
-
Why convert megohms to volt/ampere?
-
Converting to volt/ampere helps express high electrical resistance values in the standard SI unit for better precision and consistency in circuit analysis.
Key Terminology
-
Megohm
