An ammeter measures current THROUGH a circuit, a voltmeter measures current ACROSS a circuit.
The ammeter is connected to a power source in series, essentially actually becoming part of the circuit. The current is flowing directly through the ammeter as if there were a wire in its place. If there is a surge from a substantial power source, the ammeter would be destroyed and the user could be severely injured.
The fuse will "blow" if its "load" is exceeded breaking the circuit.
A volt meter is connected to a power source in parallel because it has an extremely high resistance and little to no current would get through. You don't need a fuse because the current doesn't flow through it openly.

Can you use 600 volt fuses in place of 250 volt fuses on a 208 Volt System?
Answer for USA, Canada and countries running a 60 Hz supply service.If they fit, which I doubt, yes, you can use 600 volt fuses in place of 250 volt fuses so long as the amp rating is correct.YOU CANNOT USE 250 VOLT FUSES IN PLACE OF 600 VOLT FUSES !!!You can use a fuse with a higher volt rating but not a smaller volt rating than the voltage applied to the circuit.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Can you measure power with a volt meter?
No. A voltmeter measures potential difference (voltage). To measure power, a wattmeter is required. On the other hand, for a d.c. circuit only, you could use a voltmeter and an ammeter, and multiply their readings in order to calculate the power of a load.
How do you read 208 volts single phace circuit?
All voltage reading are usually read with a volt meter. This volt meter can be a hand held unit like electricians use.
Why the windings of an ammeter should be of thick wire?
because lots of current is likely to be flowing through them.however a shunt ammeter is easier to build than the direct ammeter as described above. in a shunt ammeter you use an ordinary meter wound with fine wire and put a small value shunt resistor across it to take almost all the current.
Can a voltage tester be used for precise voltage measurements?
Depends on the test instrument and the currents involved. I use a fairly inexpensive digital volt/ ohm meter, and it reads in 1/10 of a volt increments.

How increase the range of ammeter and volt meter?
Through the use of a 'multiplier', i.e. a carefully-calibrated resistor connected in series with (in the case of an analogue instrument) the instrument's operating coil.
Why don't we use an ammeter in series?
You do use an ammeter in series. It has a very low resistance, which according to ohms law, makes it ideal for measuring current. You do not use a volt meter in series, as it has a very HIGH resistance and would not allow current to flow. You measure the voltage across a component (or components), and current through a circuit.
What piece of equipment would you use to measure the current in a circuit?
There is a tester normally called a "volt meter" or "multi meter" that you can buy at any home supply or hardware store that has both voltage (AC and DC settings) amperage, and ohms, which is the amount of resistance in a wire.
How do you check for amps?
You need to use an ammeter - usually the current setting on a multi-meter. The meter should be connected to the circuit in series.
Can you use an Amp meter to read energy with fruits and vegitables?
No but you can use a volt meter to read voltage.
How do you check the 120 volt plug on 1994 diesel club wagon?
Use a volt meter Plug a 120 volt accessory into it

What do electricians use to test circuits?
Continuity tester, volt meter, clamp on amp meter, megger and ohm meter.
Voltmeter is used for?
A volt meter is use to measure the voltage of the circuit.
When measuring current always place any type of meter in?
No. When measuring current, use an ammeter and place it in series in the circuit.
