If you hold the test leads of an ohm meter together the resistance should go to zero ohms or very close. If it doesn't you're ohm meter is malfunctioning.
ANSWER: Actually that is the first thing to do. It should show a zero reading If not the meter needs calibration adjustment. Otherwise the reading will be off by the that amount as true value.

What refers to the tendency of oil to resist flowing?
Oil viscosity depends on it's temperature. The higher the oil temperature is, leads to higher viscosity and low flow resistance. Cold oil temperature leads to lower viscosity and higher flow resistance
What type of curcuit measurement is made by placing a meters test leads in parallel with a deenergized component?
Continuity, resistance?
A measurement of 200 ohms is obtained between the primary and secondary of a double wound transformer is it safe to use?
When a resistance measurement is taken from both primary leads tied together to both secondary leads also tied together in a transformer, and the resistance obtained is 200 Ohms -- not safe in my book.

What is relationships of capacitive reactance to resistance?
when ever current passing through any two parallel transmission line than due to the dieletric property of conductor some what capacitance effect will be generate between them that phenomina called as capitance reactance/////////////////// that symply we can called capitance reactance is measure of capitance The reactance of a capacitor is its resistance.
How many test leads are needed to find resistance?
The test equipment needs two test leads to find the resistance in a circuit.
What varies as you press the leads of a multi-meter with your fingers?
The resistance of your body affects the measurements taken by the multimeter. By pressing the leads with your fingers, you introduce a parallel resistance path to the circuit being measured, leading to inaccurate readings. It's important to maintain a consistent contact pressure and use appropriate accessories to minimize errors.
What part of the ohms scale of a meter are the most accurate resistance measurements made?
It really depends on what you are trying to get the resistance of. A piece of copper wire 30 feet long will only have a resistance of few ohms. A person can have a resistance of several million ohms. Making sure that your meter's leads are in good contact with whatever you are measuring is the best way to get an accurate reading.
Insulin deficiency or resistance leads to hyperglycemia and ketoacidosis?
Diabetes Mellitus
What is the resistance of two extension leads of 95 ohms and 75 ohms when connected together in series?
The resistance across both leads would be cumulative. 95+75= 170 Ohms
When the leads of the meter are touched together a nd the meter is set to measure resistance what should the resistance reading be?
Zero ohms.
When performing a diode test is necessary to?
A diode should show low resistance with the leads hooked one way and show an open with the leads reversed
Why one of the leads of resistor connected in electronic circuit is opened while measuring its resistance?
You open one of the leads of resistor connected in electronic circuit while measuring its resistance in order to not introduce error cause by other components in the circuit.
What refers to the tendency of oil to resist flowing?
Oil viscosity depends on it's temperature. The higher the oil temperature is, leads to higher viscosity and low flow resistance. Cold oil temperature leads to lower viscosity and higher flow resistance
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 happens to electrical resistance of most conductors when heated?
Resistance goes up creating more heat which eventually leads to an open circuit.
What is the function of compensating leads in the platinum resistance thermometer?
Compensating leads help to reduce errors in temperature measurement by minimizing the impact of lead resistance on the overall measurement. They are made of the same material as the sensor to maintain consistency in resistance, ensuring accurate temperature readings.
