What are the expected readings of the ammeter and voltmeter for the circuit in the figure below? Ammeters and Voltmeters: Ammeters and voltmeters are the fundamental measurement instruments in electrical circuits. An ammeter is placed into a circuit in series with ...
Ideal meters (e.g. ideal voltmeters and ammeters) are an informative guideline that informs the design of electrical meters. Ideality in this sense means that the meter does not interfere with the measurement. In the case of an ammeter, which is...
The utility model relates to an AC/DC voltmeter and ammeter based on a single chip microcomputer and an optical coupler and a sampling circuit, which comprises a rectifier bridge, a resistor, a switching power supply, an optical coupler, a single chip microcomputer and a digital display circuit...

In summary, the circuits in the project are A/V transmitters with an impedance of 75 ohms. The project uses a 4.2V mini-USB and a 3.7V lipo battery. The resistor in the circuit is 470 ohms and the goal is to calculate the current throughout the circuit without using an ammeter....
The term cosφ is called the power factor (often designated as PF) and is, by definition, the ratio of the real power to the apparent power, real power being equal to the power measured by a wattmeter and apparent power being calculated from ammeter and voltmeter readings. The actual value...
