Use a shunt made a precision but very low resistance. Place the shunt in series with the ckt. Measure the voltage drop, and do the math.
The ammeter function of most voltmeters uses two ranges- about .25ohms for the 10 amp range, and a higher value for lower currents on the order of 250ma where a larger shunt won't affect the ckt too much and give a more accurate reading. Many meters are damaged when this function is used on low range first with 10 amps applied!

What function in a circuit for a switch?
A switch is a make - break device. Its function is a circuit is to make and break the current flow of the circuit that it is in. This action then starts and stops the load that is connected in the circuit.
Why does a switch make a light turn on and off?
The purpose of a switch is to stop and start a current flow in a circuit. The stopping of a current flow in a circuit effects the load of the circuit by stopping its action. Resuming the current flow in a circuit also resumes the action of the load.
Multimeter that can measure inductance capacitance frequency voltage current and resistance in one system?
Many mutlimeters have this capability. You'll probably want a digital multimeter. If you do a good search, this should be easy to find. You'll need to read through the specifications carefully to make sure you find one that gives the level of accuracy you're looking for. the more accurate it is, the more you'll pay.
What are the precaution before using a multimeter dc voltmeter and dc ammeter?
Make sure the the Leeds are inserted in the right hole. Make sure that the meter is set to the range of voltage or current you expect
How do you measure a resistor using multimeter?
a multimeter probably has a Ohm meter as well. If yes, use it and make sure you have the correct scale adjusted. If there is no Ohm meter you should calculate the resistance using Ohms Law. So if you use your multimeter as an Amp meter (in series with the unknown resistor) and you apply a know voltage across you should be able to calculate the resistance by dividing the voltage you applied by the current you meassured (R=v/I) ANSWER: 1 make sure ther is no external power connected 2 short the leads together and adjust for zero reading on the meter. This step is necessary to eliminate the internal battery drifting with time. Unlike voltage and amps reading the scaling of the meter is not important to begin with since a peg meter or a overflow will not destroy the meter immediately but do change the scale to get maximum deflection or digital display.That it
How do you use a multimeter to measure electrical current?
To measure electrical current using a multimeter, set the dial to the current measurement setting, typically labeled as "A" for amperes. Then, connect the multimeter in series with the circuit you want to measure. Make sure to follow proper safety precautions and never measure current on a live circuit. Read the current measurement displayed on the multimeter screen.
How can I accurately measure amps on a 240V circuit using a multimeter?
To accurately measure amps on a 240V circuit using a multimeter, you need to set the multimeter to the current (amps) setting, then connect the multimeter in series with the circuit. Make sure to follow safety precautions and consult the multimeter's manual for specific instructions.
How do you check amp draw?
Amperage is measured by a multimeter. First determine the amperage rating on the multimeter. Next, select the appropriate setting on the tool. The next step is to set the range on the multimeter. Make sure to plug the leads into the appropriate terminals. Run the circuit through the multimeter to measure the current. Turn off the breaker, make sure the AC circuit is turned off, then rewire the circuit.
Measure battery current?
To measure battery current, you can use a multimeter set to measure current in series with the battery. Connect the multimeter in series between the battery and the load to measure the current flowing from the battery to the load. Make sure to select the appropriate current range on the multimeter to avoid damaging the instrument.
What purpose might the multimeter serve in maintaining and troobleshooting a computer network?
With the multimeter you can measure the voltage on parts of the circuit board. You can also measure the resistance of resistors and make sure there are no short circuits in the circuit.
How do you measure volts accurately in an electrical circuit?
To measure volts accurately in an electrical circuit, you can use a digital multimeter. Set the multimeter to the voltage setting, connect the probes to the circuit's positive and negative terminals, and read the voltage displayed on the multimeter screen. Make sure to select the appropriate voltage range for the circuit you are measuring to ensure accurate results.
How to measure voltage accurately in an electrical circuit?
To measure voltage accurately in an electrical circuit, use a digital multimeter set to the voltage measurement range. Connect the multimeter's probes across the component or points where you want to measure the voltage. Read the displayed voltage value on the multimeter's screen. Make sure to select the appropriate voltage range on the multimeter to get an accurate measurement.
How can you measure ac?
you can measure ac using a cathode ray oscilloscope. it will project a sinusodial waveform, showing that the current is in the positive direction in the first half and the opposite direction in the second half
How to test a circuit with a multimeter?
To test a circuit with a multimeter, set the multimeter to the appropriate setting (voltage, resistance, or continuity), connect the probes to the circuit's components, and read the measurement displayed on the multimeter. Make sure the circuit is not powered on when testing for resistance or continuity.
How do you use a multimeter to check for power in a circuit?
To check for power in a circuit using a multimeter, set the multimeter to the voltage setting, connect the black probe to the ground and the red probe to the live wire, and read the voltage displayed on the multimeter. Make sure the circuit is turned on and be cautious of electrical hazards.
How to use a multimeter to measure voltage accurately?
