5 Error Sources in Ohm''s Law Experiment [How to avoid them]
Ohm performed repeated experiments on a resistor, applied different voltages, measured current and found relationship between these quantities. He finally published the law in 1827 and generalized his observations in single statement: The current flowing through the resistor is directly proportional to the voltage applied across it.

If there is both a capacitor and an inductor, find the net voltage from these two phasors, since they are antiparallel. Find the equivalent phasor from the phasor in step 2 and the resistor''s phasor using trigonometry or components of the phasors. The equivalent phasor found is the emf of the circuit.
21.4 DC Voltmeters and Ammeters – College Physics
Note that there may be more than one answer to each part. Figure 10. 4: To measure currents in Figure 10, you would replace a wire between two points with an ammeter. Specify the points between which you would place an ammeter to measure the following.
Solved An ideal battery having emf ε is used to charge
After switch S1 has been closed a long time, capacitor C1 acquires a charge of 2.10×10-5C and C1=3.50×10-6F.Assume capacitor C2 is initially uncharged. As shown in Figure 2, ... There are 2 steps to solve this one. Step 1. The correct answer is (b) electric potential difference. When two capacitors are connected in paralle ...

Ammeter
In this ammeter configuration each shunt resistor, R S of the multirange ammeter is connected in parallel (shunted) with the meter as before to give the desired ampere range. So if we assume our 100uA FSD meter from above is required to measure the following current ranges of 1mA, 10mA, 100mA, and 1A, then the required shunt resistors are …
Measuring Voltage, Current, and Resistance
So if there are multiple current paths between the measurement points, your reading of resistance could be faulty. In a series circuit, this will not present an issue. However when measuring resistance in parallel circuits, it is best to either completely disconnect the component or section of the circuit to be measured.

If there is both a capacitor and an inductor, find the net voltage from these two phasors, since they are antiparallel. Find the equivalent phasor from the phasor in step 2 and the resistor''s phasor using trigonometry or components of the phasors.
Series circuits
That''s because the potential difference now has to be shared between two of them, and there''s more resistance in the circuit, reducing the current. You can see that the ammeter reads nought ...

Measuring Voltage, Current, and Resistance
A short circuit occurs when there is zero resistance where there should be some resistance. Sometimes this can indicate a serious issue like an electrical arc has occurred. For instance, capacitors should have infinite resistance. If a capacitor is reading zero, or a small number of Ohms, the capacitor has most certainly failed.

B10: Resistors in Series and Parallel; Measuring I & V
There are only two wires (conductors) in this circuit. I am going to highlight them in order to make my next point: Highlighting the conductors makes it obvious that the voltage across (R_{12}) is the same as the voltage across the seat of EMF because, in both cases, the voltage is the potential difference between one and the same pair of conductors.
How Capacitors Work
A 1-farad capacitor can store one coulomb (coo-lomb) of charge at 1 volt. A coulomb is 6.25e18 (6.25 * 10^18, or 6.25 billion billion) electrons. One amp represents a rate of electron flow of 1 coulomb of electrons per second, …

AC electromechanical meter movements come in two basic arrangements: those based on DC movement designs, and those engineered specifically for AC use. Permanent-magnet moving coil (PMMC) meter movements will not work correctly if directly connected to alternating current, because the direction of needle movement will change with each half …
