Earth ground resistance.
There is not one standard ground resistance
threshold that is recognized by all agencies.
However, the NFPA and IEEE have recommended
a ground resistance value of 5.0 ohms
or less.
The NEC has stated to "Make sure that system
impedance to ground is less than 25 ohms
specified in NEC 250.56. In facilities with sensitive
equipment it should be 5.0 ohms or less."
The Telecommunications industry has
often used 5.0 ohms or less as their value for
grounding and bonding.
The goal in ground resistance is to achieve
the lowest ground resistance value possible
that makes sense economically and physically.

What reverse resistance reading should diodes have when under test with an ohmmeter?
Reverse resistance should be infinite.
What is the maximum resistance you want to see across a switch?

Where do you set the dial when you are measuring resistance on house current?
YOU DO NOT "measure resistance on house current".You never measure resistance of anything that has any path to any source ofpower ... not to a wall outlet, a battery, a windmill, a solar panel, etc. You onlymeasure resistance when all power is REMOVED from the circuit or componentyou're measuring. Then, the range you choose for the ohmmeter depends onthe component or circuit you're measuring, NOT on how it's powered when it'sturned on.
What type of test should a megohmmeter be used on?
Insulation resistance.
Between what values should the safe reading of insulation resistance of a domestic house?
Between .5 meg ohms to 2 meg ohms is a safe range for your house wiring insulation. Infinity is the ultimate.

Which member of the House of Burgesses called for resistance to the Stamp Act?
Patrick Henry, one of the members of the House of Burgesses, called for resistance to the tax. He gave the famous speech "Give me liberty or give death"!

Who built the hiding place in Corrie Ten Boom's house?
The Dutch resistance.
What is the maximum resistance you want to see across a switch?
The maximum resistance across a switch should be infinite.
The resistance of earth wire is?
The recommended resistance that one should strive to obtain is zero.
When measuring resistance what should done to the supply voltage?
supply should be off
What should the resistance on a 30 amps triple pole contactor measure?
If the coils pulling the contactor in, you should have negligible resistance. If the contactor is not in, then you should have open circuit. Unless your measuring the resistance of the coil, in which case it will roughly be around 30ish ohms im guessing, depends on the coil voltage
How can you measure internal resistance of car battery?
You measure it indirectly using a known load resistance and measuring supplied current. Loading of the ammeter should be known as well, and the load resistance should be made relatively small to get accurate results.
Where should the fulcrum be placed in a first class lever to make the resistance easiest to move?
The fulcrum should be placed closer to the resistance to make it easier to move when using a first-class lever. By positioning the fulcrum closer to the resistance, you can gain a mechanical advantage, requiring less effort to move the resistance.
