List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
Ideally the measuring device should not affect the circuit parameters i.e., the internal impedance of the ammeter should be zero (no voltage drop over the ammeter) and the internal impedance of the voltmeter should be infinite (no current through the voltmeter). However, in actual case, ammeters have a low but non zero impedance and voltmeters ...
A voltmeter is optional since the applied voltage is the same as the voltmeter reading. Now with the help of a variac, the applied voltage is slowly increased until the ammeter gives a reading equal to the rated current of the HV side. After reaching the rated current of the HV side, all three instruments reading (Voltmeter, Ammeter, and ...
For example, a multimeter which can read up to 19999 (plus an embedded decimal point) is said to read 4 + 1 ⁄ 2 digits. By convention, if the most significant digit can be either 0 or 1, it is termed a half-digit; if it can take higher values without reaching 9 (often 3 or 5), it may be called three-quarters of a digit.
where is an initial direct measurement of by the system voltmeter and the "Round" function means rounded to the nearest integer. The direct measurement of V R {\displaystyle V_{\text{R}}} is obtained by setting the array to the n = 0 {\displaystyle n=0} step, which can be seen from Fig. 7 to connect the voltmeter directly to the Zener reference.

A voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit. It is connected in parallel . It usually has a high resistance so that it takes negligible current from the circuit.
SCPI commands to an instrument may either perform a set operation (e.g. switching a power supply on) or a query operation (e.g. reading a voltage). Queries are issued to an instrument by appending a question-mark to the end of a command. Some commands can be used for both setting and querying an instrument.
