When using a multimeter to measure a dc current are the terminals polarity conscious?

Yes, if they are reversed the reading is also reversed. On a digital meter this will usually be displayed as a negative value, but on the older style mechanical analog multimeters it may actually damage the meter by "pegging" the needle in the backwards direction and bending it causing all future readings to be wrong.

What are the used of multimeter?
to check voltage, current , polarity of of material,etc
How can you check Integrated Circuits with a multimeter?
To check the IC by the multimeter, you have to make sure that the pointer points at the current. You can then connect the multimeter across the check the IC.
What does MA mean on a multimeter?
MA or mA on a multimeter designates milliamps, or "thousandths" of an amp of current flow.
What is the common use for a multimeter?
A multimeter is used to measure various properties of electricity. The "multi" refers to it multiple functions which can range from volt meter, current meter, resistance meter. The most common use would depend on the users preference to what is needed and measured most frequently.
Why resistor do not have positive or negative terminal?
cuz a resistor is basically a long wire , that resists some of the charges flowing across it. it has resistive properties which stops some of the current from flowing from one terminal to the other. so....as it is just a piece of wire....it doesn't need a +ve or a -ve terminal

When testing for current draw your digital multimeter should be set on?
When testing the current draw your digital multimeter should be set on the current.
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.
Which current is having high polarity?
ac(Alternating Current ) has the high polarity.
What else can a multimeter measure?
current.
What should the multimeter be set on to measure charge?
Current is measured in amps so the setting on a multimeter would be A Measuring current with a multimeter is only to be done by someone with training because it can be very dangerous It is much better to measure current with a clamp meter
Explain welder polarity?
Welder polarity has to do with DC (Direct Current) welders. Essentially, polarity is the direction of the current. Straight polarity means that the current is running from the electrode, to the metal, and back through the grounding clamp. Reverse polarity means that the current is going the opposite way, from the grounding clamp, through the metal, and up through the electrode.
What is the symbol of current in multimeter?
A Giant Penis
Will changing the polarity of the current change the polarity of the electo magnet?
Yes!

What does MA mean on a multimeter?
MA or mA on a multimeter designates milliamps, or "thousandths" of an amp of current flow.
What is the purpose of an automotive multimeter?
An automotive multimeter, like any multimeter, can be used to test the voltage or current in some kind of circuit. As it is an automotive multimeter it is aimed more towards the used in a car.
