What ohms setting do you use on a meter for 240v electric heater?
Whenever you use an ohmmeter, you must first ensure that the device you want to test is disconnected from the supply. So the fact that your heater is rated at 240 V is irrelevant to this question. The heater must be disconnected from the supply BEFORE you contemplate measuring its resistance. Which 'ohms setting' to use is then simply determined by whichever setting gives you the best reading. For an analogue ohmmeter, this is whichever setting results in the pointer being towards the lower-resistance end of the scale.
What is a diode check setting used for on a dvom?
The Diode Check setting on a DVOM is a special ohms setting that presents enough voltage to the tested device to conduct, if it were a diode. Old style VOM's did not have this problem, because they usually used a battery greater than 0.7 volts to run the ohm's scale. Modern DVOM's, however, can use very small voltages to measure ohms, and that would not cause a diode to conduct. The Diode Check setting fixes this limitation.
How do you test a good and working contactor?
A contactor is tested by using a device called a Multimeter. By setting the multimeter to ohms and rx1 you can clip both prongs to the coil. If the multinmeter moves the contactor is good. If it doesnt move its bad.
What law would you use to determine the voltage of a power supply?
ohms
What Transistor to use from 10 ohm to 4 ohm?
We do not use transitors from 4 to 10 ohms. We use resistors.

What is the 20k and 200k setting on a digital ohm meter?
20k is equal to 20,000 ohms (20 kilo ohms) and 200k is equal to 200,000 ohms (200 kilo ohms) of electrical resistance
How do you know that the sensor is bad?
Find out the ohms range it must be within and do an ohms test.
What is an easy way of understanding which fruit conducts electricity best and how do you do it?
Find a digital multimeter (fairly inexpensive) and stick the test leads into different ends of a piece of fruit. Use the "ohms" setting on the meter. The fruit that has the lowest reading will have the best conductivity.
How do you test resistance in a circuit?
With a meter that measures Ohms.
What is the output voltage of an insulation tester which is required to test a 230v circuit?
On a hand crank megger which is used to test insulation breakdown, use the 300V setting. If the megger does not have that setting use 500V as opposed to 1000V for the test. The output of the megger is a DC voltage.
What are the applications of decade resistance box?
A decade resistance box is piece of laboratory equipment that allows the user to dial in a precise amount of electrical resistance to be inserted into a circuit. For example, it might have a dial for 100s of Ohms, 10s of Ohms, and 1s of Ohms, and allow the user to set any value from 999 Ohms to 0 Ohms in 1 ohm steps. While the use of this device has probably been largely superseded in laboratory use by more sophisticated equipment, it was used in the past in some or all of the following applications: Measurement of unknown resistances by the "bridge" method, Setting the current in a test circuit, Calibrating other lab equipment such as an Ohmmeter or Ammeter, Demonstrating Ohm's Law, and so on.
What equation do you use to find ohms?
Use the equation that shows the relationship between ohms and the properties that are known.

How do you test a speaker crossover?
You want to test resistance to see if there is a break in the windings. Set your voltmeter to Ohms.
How can you tell you have a bad coil on a 1968 Mustang?
Test it Primary resistance 1.40 to 1.54 ohms secondary resistance 7600-8800 ohms primary circuit resistor 1.30 to 1.40 ohms
