What are applications of OHM METER?
It measures resistance in a component or circuit to determine if there is a break in that circuit or component. If there's no resistance, it means there's a break, as no electrical current is passing through.
What does a megohmeter or megger test?
It checks resistance from a circuit or an electrical component to earth, to make sure it is electrically isolated. This must be a very high value of resistance, hence 'megohms'.
What is the unit used of resistor?
The ohm. It is how much resistance a component or part of a circuit has to the flow of electrical charge when a voltage is induced across it.
What is resistance expressed in?
Electrical resistance is measured in Ohms.
What is excessive electrical resistance?
High resistance means insulation

What is ohmmeter?
An ohmmeter is a type of electrical metre that measures electrical resistance. When in resistance-measuring mode, multimeters also operate as ohmmeters. An ohmmeter measures the resistance of a circuit or component by passing electricity through it.
How many ohms does your Jeep Wrangler have?
Sorry but your question does not contain enough information to be answered. Ohms are a measurement of electrical resistance. Please specify the electrical component that you wish to know the Resistance of.
What is the variable resistance with 3 leads?
If when you said "resistance" you actually meant resistor, this component is called a potentiometer (see image for an example).If that is not what you meant, then I cannot begin to guess what you are referring to, as resistance is a quantity not a component and thus cannot have physical leads (and I have been involved with electronics since 1967 and worked in the field for 30 years).
What does R mean in an electrical circuit?
it's generally the resistance. its generally the energy dissipiating component called Resistor
What is a way of saying how difficult it is for electricity to flow?
The resistance to the flow of electricity is referred to as electrical resistance. It is a measure of how difficult it is for an electric current to pass through a material or component.
What type of circuit measurement is made by placing a meters test leads in a parrallel with a deenergized component?
To measure resistance, continuity, or diode voltage drop in a de-energized component, the meter's test leads are placed in parallel with the component. This allows the meter to measure the electrical properties of the component without applying power to it.
In electrical work resistance is often represented by the?
In electrical work, resistance is often represented by the symbol "R" and is measured in ohms (Ω). It describes how much a material or component impedes the flow of electric current. The higher the resistance, the more difficult it is for current to flow through a circuit.

It checks resistance from a circuit or an electrical component to earth, to make sure it is electrically isolated. This must be a very high value of resistance, hence 'megohms'.
What is the unit used of resistor?
The ohm. It is how much resistance a component or part of a circuit has to the flow of electrical charge when a voltage is induced across it.
Resistance is measured in what?
Electrical resistance (and impedance) is measured in ohms(Ω).
Why could the total resistance of the circuit vary when measuring resistance using a multimeter?
Residence of one component varies overtime and from component to component.
