DMM (Digital Multimeter) test lead resistance should generally not exceed 0.1 ohms to ensure accurate measurements. Higher resistance can introduce significant errors, particularly in low-resistance measurements or applications requiring precise readings. It's important to periodically check and calibrate test leads to maintain their performance and reliability.

How do you know if a three phase motor's winding is shorted?
You use a megger. This allows you to check what the condition of the insulation of the motor windings are. An ohms check on each phase should be an easy way if it reads OPEN then there's your bad phase. Otherwise there are diffrent types of 3 phase motors, could be the brushes, commutator, sliprings, many many things.
Do capacitors have internal resistance?
1. The capacitor has Lead resistance in series with the capacitor2. Since most capacitor use Dielectric and they have a leakage resistance and it is parallel to the Ideal Capacitor.
Do batteries have resistance?
Yes they do have a resistance. Even though a battery is a voltage source it has some thevenin resistance. Every lead plate and cell of sulfuric acid, will have a small resistance. The thevenin resistance is equivalent or sum of all those resistances.
Why must a fuse or Switch never be fitted to the secondary of a CT circuit?
Secondary of a CT should never be opened to avoid damage to CT. Fuse or switch may lead to opening of CT secondary accidentally.
What is wrong with the sign of danger high resistance?
The sign "Danger: High Resistance" is misleading because it implies that high resistance is inherently dangerous, which is not accurate. In electrical terms, high resistance typically means less current flow, which can reduce the risk of electric shock. Instead, signs should emphasize the dangers of high voltage or low resistance, which can lead to increased current and potential hazards. Clarity in safety signage is crucial to effectively communicate risks and ensure proper precautions are taken.
What resistance should a spark plug lead have?
14-16Kohm / metre
Is lead edible?
Lead is highly toxic and should never be eaten.

What method should never be used to thaw food?
Thawing food in hot water should never be used as it can lead to bacterial growth and foodborne illness.
How should you make out if you're a girl have never made out and are nervous?
Let the guy lead you(;
How does pencil lead taste?
Pencil lead should never be consumed as it can be poisonous. If accidentally ingested, seek medical attention immediately.
What should the ohmmeter read when the lead probes are touched together?
When the lead probes of an ohmmeter are touched together, the ohmmeter should read close to zero ohms, indicating a short circuit or very low resistance between the probes.
Should people be treated as stocks?
No. Lead people, manage numbers, never confuse the two.
Who lead the massive resistance movement?
cheese
What happens when a boy a girl?
First, You should NEVER make the first move!! But if you do it will probably lead to sex.
What has the author John Peter Mitchell written?
John Peter Mitchell has written: 'The electrical resistance of zone refined lead and lead alloys at low temperatures' -- subject(s): Lead alloys, Physics Theses, Metals at low temperatures, Lead, Electric resistance 'The resistance of lead in the temperature range 1 to 4 degrees K' -- subject(s): Physics Theses
What senses should never be used in a laboratory?
Taste and smell should never be used in a laboratory, as they can lead to potential exposure to harmful chemicals or substances. Additionally, relying on these senses can be subjective and unreliable for accurate data collection and analysis.
