The voltage needed to make a resistance measurement varies in proportion to the Ohms value being measured. Resistance measurements in the order of thousands and up to one Megohm are low enough to be made with a 1.5 volt or similar cell. However, resistance measurements in the order of hundreds to thousands of Megohm will require a higher voltage of up to 500 Volts DC. A Megger is a device that uses hundreds of volts to make resistance measurements.

What is the ohm unit used to measure?
Ohms measure electrical resistance. The resistance in ohms is the voltage divided by the current.
What are three test that the digital multimeter is used for?
To measure voltage, current and resistance.
How and what is a multimeter use for?
a VOM is typically used to measure resistance, potential (voltage) and current (amps).
What volts ohm ampere and watts are terms associated with this?
ohm is used to measure resistance of electric current. Ampere is used to measure electric current. volt is used to measure voltage.
Volt ohm ampere and watts are terms associated with what?
ohm is used to measure resistance of electric current. Ampere is used to measure electric current. volt is used to measure voltage.
What is used to measure voltage?
a voltmeter is used to measure voltage
What is the function of vom in electronics?
Measure voltage, resistance, and on some meters current. Typically used as a troubleshooting aid.
What are the three main function of the multimeter?
A typical multimeter can measure: * AC & DC voltage (volt) * AC & DC current (amp) * resistance (ohm)
What instrument used to measure alternating current?
A multimeter has the ability to measure both AC and DC current along with voltage and resistance.
Can 50 Hertz multi tester be used on 60 Hertz 220 volts for testing voltage?
Any of the multi testers that I have come across are not frequency sensitive. I use a Fluke process meter and it can be used to measure frequency if that scale is selected. Voltage is voltage, amperage is amperage and resistance is resistance regardless of what he frequency is.
What is the use of resistance box?
The use of a resistance box or a "Decade Box" is to help calibrate instruments used to measure electrical values such as Voltage, Current, and Resistance. Without them you would not have a known value of resistance to use as a set point.
Why can't you use a multitester as an ohmmeter if it has no battery?
The battery is used by the meter to apply a voltage across the resistance being measured and determine the current which determines the resistance. If there is no battery it can't supply the voltage and can't measure current, so no reading.
