What is an automotive ammeter?
An automotive ammeter is a device used to measure the electrical current flowing in an electrical circuit. In the context of automobiles, it is wired to show whether the battery is discharging, charging, or neither. Cars and trucks have two power sources: the battery and the alternator. The output wires for the battery and alternator are joined to the wires feeding the key switch, the headlights, and the fuse box at one or more junctions.
What is the function of an ammeter?
It clearly follows that the function of an ammeter is to measure that current within an electrical circuit. Ammeters measure current in two metrics - ‘draw’, the flow of current in a particular circuit, and ‘continuity’, the steadiness of the current and the presence or absence of interruptions.
How do you use an ammeter?
Apply the ammeter leads to the target area - the point at which you want to measure the current. Using a crocodile clip, attach the red lead to the wire nearest the positive terminal and the black lead to the wire nearest the negative terminal on the device you are measuring. Be careful not to confuse the two Check your reading.
What is an ammeter in a main charge circuit?
An ammeter in a main charge circuit measures the electrical flow. It is a device that responds to electrical current by moving a needle. In the most common automotive ammeters, the needle is deflected by the small magnetic forces created when current flows through the meter. These meters are placed directly in the flow path being measured.
What is the difference between a voltmeter and an ammeter?
An ammeter is used to measure small amounts of current, typically displayed in milliamperes. It is connected in series with the circuit to ensure the entire current flows through it. A voltmeter, on the other hand, is connected in parallel with the circuit to measure the potential difference between two points.
What is ammeter reading?
Ammeter reading is the reading of the deflection of the magnetic needle due to the intensity of the magnetic field created in the ammeter coil caused by the amount of current flowing. So when calibrated they are capable of measuring the amount of current flowing when connected in series in the circuit.
