How does DC Volts Amp Meter Work. #viral #multitech #science.




A DC ammeter is an instrument which is used to measure the amount of DC current flowing in a circuit. The DC ammeter has a scale which represents current in ampere. An ammeter measures the current in a circuit, while a voltmeter measures the potential difference between two points in a circuit. Answer: An ammeter is placed in series with the circuit component being measured.The other “V” symbol is for DC voltage. The AC voltage symbol will be a “V” with a “∿” over the V. The DC voltage symbol will be a “V” with a solid and dashed line over the V. Negative of the load to be connected to the thick red wire. So this goes in series now you can see the reading it is around 2.9 amps and there is a slide up in the voltage it is around 11.7 volt. Both of these devices are used in electric circuits but the major difference between a voltmeter and an ammeter is ammeter comes in handy for measuring the flow of current whereas the voltmeter comes in handy for measuring the voltage or emf across two points in an electric circuit.Direct current is fairly straightforward. DC power strictly flows in one direction. That means the electrons get pushed in from the power generator, and keep going forward through the wire until it gets to your device, does its work, then continues through the outlet to complete its circuit. ammeter, instrument for measuring either direct (DC) or alternating (AC) electric current, in amperes. An ammeter can measure a wide range of current values because at high values only a small portion of the current is directed through the meter mechanism; a shunt in parallel with the meter carries the major portion. The formula for electric current is I=V/R. Solar panels generate DC, whereas households primarily consume AC. Thus, inverters convert solar energy into a form that is usable in your customer's homes. Batteries produce direct current (DC). Thus, a battery only provides direct current, or DC.12 VoltDirect Current (DC). 12 volt is the type of electricity you would find in an automobile. Your battery is the foundation for the 12 volt system in your RV. A fully charged battery will operate the 12 volt equipment (furnace, water heater, most lighting, range hood, monitor panel, roof vent fans, etc.)The major use of DC is to supply power to electrical devices and also to charge batteries. Example: mobile phone batteries, flashlights, flatscreen television and electric vehicles. AC amps and DC amps are more or less the same things. They are both measurements of electricity flowing through a circuit. The only difference between the two would be the flow of the electrical current itself. DC amperage means the flow of electricity only moves in one direction at a particular frequency. In a DC circuit, all the derivations of the power formula combined with ohms law can be used such as Power = V*I, Power = I2R, and Power = V2/R. The units of DC power are Watts [named after James Watt (17361819)]. DC power can be thought of as power consumed by a resistor. Advantages of alternating current over direct current: AC is less expensive and easy to generate than DC. AC can be transmitted across long distances without much energy loss, unlike DC. The power loss during transmission in AC is less when compared to DC. For 12V Wiring on DC Circuits, Red Is Positive, Black Is Negative.
