If there is no current flowing out of the battery, ohm law says that there is no voltage drop in R1. Thus the output voltage of the battery is V0: the nominal voltage of your battery. You are talking about a "singularity" here ...
According to Ohm's law V=IR. This means that if the current is zero there is no voltage. Does this mean also that an unplugged battery has zero voltage? Then why does it say otherwise in the package. What does it mean that a battery is 1.5 Volts if, after all, it depends on the resistance?
Now at the other end at the short circuit current the Voltage is zero, it means you have drawn out so much current that the voltage created by rI or (voltage drop due to the internal) resistance is equal to the electromotive force and a equilibrium is reached.
A battery is an approximate voltage source, not a resistor and thus does not obey Ohm's law. For an ideal voltage source, the voltage across is independent of the current through; the voltage across is what it is regardless of the value of the current through.
the battery emf causes the current, not the terminal voltage. If you short-circuit the battery, the emf drives a large current through the internal resistance and the short-circuit, but the terminal voltage is zero.
Physical voltage sources, such as a 1.5V battery, cannot supply unlimited current and, in fact, produce a finite current when short-circuited. So, we typically model a physical battery by placing a resistor in series with the voltage source. But this is the topic of another question. The battery voltage is defined by its chemistry.
Eventually, with a shorted out battery the current taken is at maximum but the terminal voltage is zero. ... The graph that you have there it shows the LOAD line, the voltage …
As the voltage applied to the circuit increases, the current remains essentially zero, until the voltage reaches the breakdown voltage and the diode conducts current. When the battery and …
Applying Kirchhoff''s current law, you can check it for yourselves. No matter your circuit and its operating conditions, the current going out of the battery should be equal to the …
If your 12V battery charger shows a charging voltage you can expect it to be around 14.0 to 14.8V for a typical Flooded lead-acid battery. If you have a 12V battery monitor (the best 12V Bluetooth battery monitor are the BM6, followed …
Coulomb counting: This method involves tracking the current flowing in and out of the battery by integrating it during use. It provides a more accurate measurement of the …
The key difference with a real battery is that the voltage across its real terminals depends on what is connected to the battery. In the example above, the battery has a voltage …
$begingroup$ the battery emf causes the current, not the terminal voltage. If you short-circuit the battery, the emf drives a large current through the internal resistance and …
Under constant voltage conditions (cv generator) the current stops because the voltage difference between the generator and the capacitor reaches zero. Under constant …
The total voltage drop across the internal resistance is again given by Ohm''s law: $$ V_s = V_0/R_s $$ The net effect of this is that the total voltage you''ll see across the terminals of the battery will drop as you draw …
The voltage across the (ideal) battery is independent of the current through. That is to say, the battery is not an ohmic device and thus, does not ''obey'' Ohm''s law. In other words, the voltage across the (non-zero) …
Consider a circuit with a battery V, resistor R, and superconductor in series. The current in the superconductor is $I=dfrac{V}{R}$, the voltage on the superconductor is zero. …
No Current Flow: A battery may have voltage but not deliver current due to internal resistance or damage. High resistance can prevent current from flowing even if a …
$begingroup$ the battery emf causes the current, not the terminal voltage. If you short-circuit the battery, the emf drives a large current through the internal resistance and the short-circuit, but the terminal voltage is …
Yes, the terminal voltage of a battery can be zero when there''s no chemical activity to create current. This situation happens if the battery is fully discharged or damaged. …
A volt is a potential difference across a conductor when a current of one ampere (Amp) dissipates one watt of power. Voltage is then defined as the pressure that pushes electrons (current) between two points to …

it doesn''t really matter what the voltage is set to on your power supply when you''re running it in constant current mode. If you want to charge the batteries up to 2V, maybe …
According to Ohm''s law V=IR. This means that if the current is zero there is no voltage. Does this mean also that an unplugged battery has zero voltage? Then why does it …
However, current more than likely won''t (depending upon the age/use of the battery). The reason why is because the voltage potential difference - the "excess holes on the …
