Multiply the amount of the current by the amount of resistance in the circuit. The result of the multiplication will be the potential difference, measured in volts. This formula is known as Ohm's Law, V = IR.

Measuring potential difference Potential difference is a measure of how much energy is transferred between two points in a circuit.

A fully charged battery will typically display a voltmeter reading of about 12.6 to 12.8 volts. If your voltmeter is showing a voltage anywhere between 12.4 and 12.8, that means your battery is in good shape.

2) Take a Voltage Reading If your battery is: Reading 0 volts, chances are the battery experienced a short circuit. Cannot reach higher than 10.5 volts when being charged, then the battery has a dead cell. Fully charged (according to the battery charger) but the voltage is 12.4 or less, the battery is sulfated.

The potential difference between points A and B, VB − VA, defined to be the change in potential energy of a charge q moved from A to B, is equal to the change in potential energy divided by the charge, Potential difference is commonly called voltage, represented by the symbol ΔV: ΔV=ΔPEq Δ V = Δ PE q and ΔPE = qΔV.

The potential difference is the measure of energy between any two points on the circuit. ... The EMF is the maximum voltage that the battery can deliver whereas the magnitude of the potential difference is always less than the maximum possible value of emf.

The electric charge that has been separated creates an electric potential difference that can be measured with a voltmeter between the terminals of the device. The magnitude of the emf for the battery (or other source) is the value of this 'open circuit' voltage.

Set your meter to measure in volts. Locate the positive and negative terminals of your lithium ion battery. These will usually be located on the end of your battery that slides first into the device it powers. The terminals are tiny, but they are clearly marked with a positive and negative symbol.

If a graph drawn between the potential difference and current the graph is found to be straight line passing through the origin. From graph we see that Potential difference(V) and current( I ) directly proportional to one another.

To check a car battery, turn off the ignition and pop your vehicle's hood. Hook up a voltmeter to the car's battery by connecting the red lead to the positive terminal and the black lead to the negative terminal. If the battery is in good condition, the voltage will read between 12.4 and 12.7 volts.

Potential differences (voltage) The potential difference (or voltage) of a supply is a measure of the energy given to the charge carriers in a circuit.

Observe the voltage readout on the meter. This indicates the charge of your battery. Should you see a reading of at least 12.6 volts, then your battery is fully charged. Any number lower than 12.6, however, indicates a battery that is not holding a full charge.

Look for a plus symbol on your battery. On AA, AAA, C, and D batteries, the positive end should be slightly raised. The negative end of the battery should be flat, and it may or may not be marked with a minus, or -, symbol.

The potential difference is V=IR=0.1*5=0.5V, which basically means the statement above is incorrect. I'll assume you know that your supply has an open-circuit voltage of 10 V, but you don't know the internal resistance. If you measure 0.1 A, then you know the total resistance is 100 Ohms.

Electric potential is the value of the electrical potential (V) at a given point. Potential difference is just that, the difference in the electrical potential between two points (e.g., V(b) - V(a) ). Both potential and potential difference can be negative or positive or zero.
