A volt-ampere meter. You can read current in two basic ways. The harder but more accurate way is to break the line where you are measuring current and basically insert the meter into the line so all current flows through the meter. The other type is a "clamp on" meter where the meter has something like a claw that you open and encircle the wire you want to measure. You determine the current by induction. The current flowing through the wire induces a smaller current in a loop created by the clamp on device. You can only measure current in one wire at a time. For example, you couldn't just clamp over a lamp cord and read a correct current because you are encircling two wires and the current going in each direction cancel each other out.

How do you calculate amperage when given the values of watts and volts?
With an instrument called a multimeter. The single meter incorporates within it a volt meter, an ohm meter and an amp meter. For higher amperages a clamp on amp meter is recommended as the circuit does not have to be opened to take a reading.
How many volts it takes to cause a current of 1.95 amps to exist in a 200 watt lamp?
The formula to calculate the relationship between amps, volts and watts is Volts X Amps = Watts or Volts = Watts / Amps or Amps = Watts / Volts therefore; 200 Watts divided by 1.95 Amps is 102.5641 Volts.
What does 1500 watts equal in amps at 120 volts?
To convert watts to amps at 120 volts, use the formula: Amps = Watts / Volts. For 1500 watts at 120 volts, the calculation would be: 1500 watts / 120 volts = 12.5 amps.
How many watts of power are being used at 230 volts and 10 amps?
The power can be calculated using the formula: Power (W) = Voltage (V) x Current (A). In this case, it would be 230 V x 10 A = 2300 watts.
200 watts to amps 12v?
To convert watts to amps, you can use the formula: Amps = Watts / Volts. In this case, to convert 200 watts at 12 volts to amps, it would be: 200 watts / 12 volts = 16.67 amps. So, 200 watts at 12 volts is approximately 16.67 amps.

How do you convert a 50 micro-amp DC meter to a 100 milli-amp meter?
with a resistor 300K in series with the 50 micro amperes DC meter
How many volts it takes to cause a current of 1.95 amps to exist in a 200 watt lamp?
The formula to calculate the relationship between amps, volts and watts is Volts X Amps = Watts or Volts = Watts / Amps or Amps = Watts / Volts therefore; 200 Watts divided by 1.95 Amps is 102.5641 Volts.
If voltage is 12 volts and ohms is 0.5 how many amps in circuit?
Ohm's law: Volts = Amps * Ohms, or Amps = Volts / Ohms 12 volts / 0.5 ohms = 24 amps
How can you find out if your fluorescent lights are using too many amps?
The amperage is printed on the ballast. If your meter reads higher that that what is printed there, then the ballast is drawing more amps that it should.
What does 1500 watts equal in amps at 120 volts?
To convert watts to amps at 120 volts, use the formula: Amps = Watts / Volts. For 1500 watts at 120 volts, the calculation would be: 1500 watts / 120 volts = 12.5 amps.
4 volts is a many watts?
4 volts and how many amps? Watts = amps x volts. It depends on the amount of current (in Amps) flowing at 4 Volts... See Ohms Law: Watts = Volts x Amps If you have 2 Amps flowing at 4 Volts you are dissipating/consuming 8 Watts. If you have 10 Amps flowing at 4 Volts you are dissipating/consuming 40 Watts.
Using 120 volts at 12 amps is the same power as what amps at 220 volts?
6 amps.
How many amps at 120 volts equals 16 amps at 12 volts?
160 amps at 12v.
How many amps at 12 volts equals 16 amps at 120 volts?
160 amps at 12v.
How many watts of power are being used at 230 volts and 10 amps?
The power can be calculated using the formula: Power (W) = Voltage (V) x Current (A). In this case, it would be 230 V x 10 A = 2300 watts.
200 watts to amps 12v?
To convert watts to amps, you can use the formula: Amps = Watts / Volts. In this case, to convert 200 watts at 12 volts to amps, it would be: 200 watts / 12 volts = 16.67 amps. So, 200 watts at 12 volts is approximately 16.67 amps.
