$begingroup$ A lithium battery cell is 4.2V when fully charged and is 3.2V or less when it is dead. Your cell is only 2.8V so it is dead. A dead cell cannot produce much current. It also might be ruined from being discharged to a voltage that is too low. $endgroup$ –

Why is there a voltage drop across things when no current is

But this doesn''t quite make sense to me. If there is no current, why does Ohm''s Law not apply giving me a voltage drop of V = IR = 0 as there is no current? I guess more generally I''m confused as to why things with zero current going through them have a voltage drop at all as V=IR. electric-circuits; Share. Cite. Improve this question.

Ohm''s Law confusion -

$begingroup$ In the circuit you have shown, yes current does flow through the 1GOhm resistor. As to the broader question, "does Ohm''s Law apply when the resistance is infinite?", personally I''d waft that away by saying Ohm''s law only applies to circuits - an (ideal) battery standing on its own does not constitute a circuit - but there are plenty more answers to

The best way to determine if a battery can provide enough current (amps) to crank an engine and power electrical accessories is to check the battery''s reserve capacity (RC) rating. Batteries with a higher RC will be able to start vehicles

What does it mean when a battery still has high voltage but

That would explain why the voltage is high when there is no current but why there is no voltage when there is current. The more current is drawn by the battery, the more voltage is dropped across the internal resistance and therefore the less voltage actually appears on the battery terminals.

How much voltage/current is "dangerous"?

One is general trauma - burns, etc., and that is obviously very situation and person-dependent. I''ve had shocks from 1200 VDC, 230 VAC, 50 VDC, RF, and miscellaneous other sources. No major burns. I''m still alive. Enough current for long enough to stop your natural heart rhythm and throw it into fibrillation.

How to repair when lithium-ion battery has voltage and but no current

Can A Battery Have Voltage But No Current? Easy

Yes, a battery can have voltage but no current. This happens in an open circuit. Here, the battery shows voltage, but no load is connected to draw current. Voltage measures the potential difference, while current indicates the flow of electric charge. Thus, a voltage source can exist without current under these conditions.

6 FAQs about [Battery voltage is enough but no current]

Does a battery have a voltage vs current?

Key Takeaways Voltage vs. Current: Voltage can be present in a battery without significant current (amps). Battery Health Indicators: Voltage alone is not a reliable indicator of a battery’s ability to deliver power. Internal Resistance: High internal resistance can lead to a situation where a battery shows voltage but no current.

Can a battery have voltage without significant amperage?

In wrapping up, it’s clear that a battery can have voltage without significant amperage. This phenomenon often signals issues like high internal resistance or battery wear. Understanding this concept is not just about satisfying curiosity; it’s crucial for ensuring the reliability and safety of the devices we depend on daily.

Why does my car battery have volts but no amps?

Another common reason behind a car battery having volts but no amps are bad contact somewhere between the rectifier and the load of the battery. You need to between the load and the anode bar to know if this is the case. If you see a drop in voltage when testing it, you can confirm that there’s a bad connection.

Why do batteries have a low amperage?

It’s the opposition within the battery to the flow of current. As batteries age or undergo multiple charge-discharge cycles, their internal resistance increases. This increase can lead to a situation where, despite showing adequate voltage, the battery can’t deliver enough current, resulting in no effective amperage.

What causes a battery to display voltage without amperage?

The phenomenon of a battery displaying voltage without significant amperage is primarily attributed to high internal resistance. This resistance can be caused by several factors, such as: Chemical degradation: Over time, chemical processes within the battery degrade its components, increasing resistance.

Why is my car battery not working?

The battery has enough voltage to power the lights (low current requirement) but not enough current to turn the starter motor. This discrepancy often indicates an underlying issue, like depleted battery cells or high internal resistance. Internal resistance is a key player in the battery’s performance.
