What Is Ohmmeter

An ohmmeter is an electrical instrument that measures electrical resistance the opposition offered by a substance to the flow of electric current micro ohmmeters microhmmeter or micro ohmmeter make low resistance measurements.

What is ohmmeter. Also known as electrical resistance its value is expressed in units of ohm this measurement is governed by ohm s law which states that the current passing through an electrical circuit is directly proportional to the amount of voltage exerted. In the simplest ohmmeters the resistance to be measured may be connected to the instrument in parallel or in series. An ohmmeter is a device that measures the amount of electrical friction generated as electrons pass through an electrical conductor. Micro ohmmeter is a portable device mainly used for calculating current voltage as well as for diodes testing.

The ohmmeter is very convenient to use but less accurate. Ohmmeter instrument for measuring electrical resistance which is expressed in ohms. An ohmmeter also known as an ohm meter is an instrument that measures the electrical resistance of a material resistance is a measure of the opposition to the flow of electric current. Micro ohmmeters micro ohmmeter or microhmmeter and milliohmmeters make low resistance measurements while megohmmeters a trademarked device by megger measure large values of resistance.

Megohmmeters also a trademarked device megger measure large values of resistance the unit of measurement for resistance is ohms. If in parallel parallel ohmmeter the instrument will draw more current as resistance. This type of meter comprises several selectors for choosing the preferred function and it automatically ranges to select most measurements.
