How many volts in 30amps?

All fuses have a voltage rating, which is independent of its current rating. The current rating is the maximum current the fuse will pass; any higher, and it will blow. The voltage rating is the maximum voltage that is allowed to appear across the fuse should it blow. If the voltage is any higher than the fuse manufacturer's rating, it may arc across inside the fuse, causing power to continue to be supplied to the faulty item that caused the fuse to blow in the first place. This is obviously very dangerous, and could result in severe electric shock, or fires. The voltage rating is usually stamped on one end of the fuse.


Which gives the smallest reading on a forsemeter?

An ohmmeter would typically give the smallest reading on a voltmeter compared to other types of meters like ammeters or wattmeters. Ohmmeters are used to measure resistance in electrical circuits, which can range from very low values to very high values depending on the component being measured.


How do you measure electricity and with what measurement?

With kitchen tongs. A mild tingling indicates low voltage/low amperage. Muscular spasms indicate high voltage/low amperage. Unconsciousness sans death indicates low voltage/moderate amperage. Death indicates high amperage. Good luck.

Do ammeters have batteries?

They don't need to, but if it is digital, it may have them. (Ohmmeters must have a battery)


What is the difference in series type and shunt type ohmmeter?

In a series type ohmmeter, the current passes through the resistance being measured, while in a shunt type ohmmeter, the current is diverted around the resistance being measured. Series type ohmmeters are usually less accurate but simpler, while shunt type ohmmeters are more accurate but more complex.


What is ohmmeter?

An ohmmeter is a type of electrical metre that measures electrical resistance. When in resistance-measuring mode, multimeters also operate as ohmmeters. An ohmmeter measures the resistance of a circuit or component by passing electricity through it.


What units is to meausure a ohmmeter?

An ohmmeter measures electrical resistance. This is one part of "impedance", that prevents electricity from flowing freely from one part of a circuit to another. Resistance is measured in "ohms".

How test resistances?

we can measure the resistance if we know the voltage and current passing through a line (V=IR)AnswerYou can measure its approximate resistance using an ohmmeter, but ohmmeters aren't particularly accurate. A better way would be to use a Wheatstone Bridge, which is highly accurate.

Why multimeter cannot used for measurement of insulation resistance?

Because ordinary ohmmeters are calibrated to measure a range of resistance values that are significantly lower than the resistance of insulation. It should also be realised that we usually test insulation resistance while subjecting the insulation to a high electric field, which a normal ohmmeter is incapable of producing.

What do use to measure Resistance?

To measure resistance, you could use an ohmmeter. But ohmmeters are not particularly accurate, so other methods are preferable. These include the use of Wheatstone's Bridge (which compares the unknown resistance with known values) or a Ducter (for very low resistances).
