4 Circuit Diagram Symbols: AC DC battery AC power supply DC power supply bulb resistor switch conductors (wires) A V voltmeter ammeter 5 Circuit Components: Ammeter – measures amount of current (I) Voltmeter – measures the amount of voltage (V An electronics kit in your computer! Build circuits with resistors, light bulbs, batteries, and switches. Take measurements with the realistic ammeter and voltmeter. View the circuit as a schematic diagram, or switch to a life-like view. Voltmeters and ammeters measure the voltage and current, respectively, of a circuit. Some meters in automobile dashboards, digital cameras, cell phones, and tuner-amplifiers are voltmeters or ammeters. A voltmeter An ammeter measures the electric Just like voltmeters, ammeters tend to influence the amount of current in the circuits they're connected to. However, unlike the ideal voltmeter, the ideal ammeter has zero internal resistance, so as to drop as little voltage as possible as electrons flow THE relative location, in a circuit, of a wattmeter, voltmeter, and ammeter generally requires careful consideration. If the voltmeter and wattmeter potential circuit are connected on the load side of the ammeter and wattmeter current coil, the potential You will be asked to construct several simple circuits, use an ammeter and a voltmeter to measure current through and voltage across various circuit elements, and compare your results with theoretical predictions. There are three principle objectives .

Circuits: page 3 (Videos 13 to 18: Compare bulb brightness, terminal voltage, ammeter & voltmeter) Circuits: page 4 (Videos 19 to 26: Circuits with switches, meters & capacitors, Kirchhoff's junction rule & loop rule, multiple-choice questions Here is the circuit diagram for the ammeter. Note the only change from the voltmeter is below the 10 nF capacitor at the bottom-left of IC1. The supply current will be running through the 1 ohm 5 watt resistor. In the next chapters we will discuss a A "parallel" circuit has two or more paths for the electricity. You will first wire a simple circuit which will allow you to test materials for conductivity. Next some circuits will will be used for both the ammeter and voltmeter functions. Plan, install and test power, controls, and communications circuits for substation equipment tools and test equipment in commissioning and maintenance, including volt meter, ammeter, turns ratio tester, current injection equipment, etc. .
