What is the ohmmeter reading for open circuit?
The capacitor has no resistance which your direct current ohm meter can show.
Using an ohmmeter the reading on a good 5 A fuse should be?
Using an ohmmeter, a good 5 A fuse should show a reading of 0 ohms, indicating it is a closed circuit with no resistance. If the fuse is blown, the reading would show an open circuit, often indicated by an infinite resistance or "OL" (over limit) on the meter display. Always ensure the fuse is disconnected from the circuit before testing to avoid inaccurate readings.
Is a ohmmeter a pressure gauge?
No. An Ohmmeter measures electrical resistance to the flow of current.
Why should an ohmmeter never be used on an energized circuit?
Because an ohmmeter works by putting a potential difference (voltage) across a load and measuring the resulting current (the current will be inversely proportionate to the resistance). In a live circuit there is already current flowing through the load so (at best) the reading will be inaccurate, at worst the meter will be damaged.
Should the ohmmeter be connected to the circuit while the power is being applied or only when the circuit is turned off?
Turn off the supply before using the ohmmeter,it will damaged your ohmmeter when supply is present.
When testing for electrolysis in the cooling system the digital volt-ohmmeter (DVOM) reading should not exceed?

What reverse resistance reading should diodes have when under test with an ohmmeter?
Reverse resistance should be infinite.
When using an ohmmeter what should be the results for an NPN transistor?
When the positive lead is at point "P" which is the base and the negative lead is at either of points "N" which is either the emitter or the collector, then the ohmmeter should have a very low reading or reads short circuit. Also, when the negative lead is at point "P" and the positive lead is at either points "N", then the ohmmeter should have an infinite reading when the meg ohm range.
What value will appear on ohmmeter when we will check 100 uh microhenry inductor?
The reading will be very close to zero ohms.
How can the cathode end of a zener diode be determinded using an ohmmeter?
Hard to do. If your Ohmmeter battery is just 1-1/2 volts, then you simply put the test leads on the diode one way, then the other way. The way that show a meter reading will have the black lead on the 'cathode', if you assume, as most do, that electrons are issued from the " - " or 'minus' side of the battery. BUT . . . if your Ohmmeter voltage is above the zener's trigger voltage, then you will get a reading both ways.
What is the ohmmeter reading for open circuit?
The capacitor has no resistance which your direct current ohm meter can show.
How do you connect an ohmmeter in series or paallel?
A: To read ohms you will use it by reading in parallel and without any external voltage applied
A zero reading on an ohmmeter means the circuit or component is open is this true or false?
This is false. A zero reading is what you get when you press the probes of themeter together with nothing between them, to make sure the meter is working.That's about as closed as the circuit under test can get.
Using an ohmmeter the reading on a good 5 A fuse should be?
Using an ohmmeter, a good 5 A fuse should show a reading of 0 ohms, indicating it is a closed circuit with no resistance. If the fuse is blown, the reading would show an open circuit, often indicated by an infinite resistance or "OL" (over limit) on the meter display. Always ensure the fuse is disconnected from the circuit before testing to avoid inaccurate readings.
What happen ohmmeter hook up to a live circuit?
Depending on the voltage, make sure to be safe, but I don't think that it is too bad, although it does depend on the circuit

Is a ohmmeter a pressure gauge?
No. An Ohmmeter measures electrical resistance to the flow of current.
