The volts tell you how much potential energy the battery contains, and the amps tell you how fast it can be drained. So it is impossible that a battery has voltage but no amps. A 12-volt car battery, for example, is capable of supplying a lot more power than a 9-volt alkaline battery because it has a higher voltage (12) and higher amperage ...
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.
If the voltage is absent, those electrons cannot move between points in a circuit, which means that the current does not exist. However, the voltage is still present because you have a circuit with points whose electrical potential varies. Just look at a pack of batteries. A current cannot flow unless those batteries are introduced to a circuit.
Yes, the voltage can exist without current. Every analogy you use to understand the relationship between the voltage and the current will tell you the same thing. For instance, in the case of a tap, the voltage is the pressure that forces the water out. The current is the water that has been forced out of the tap by the pressure.
A current cannot flow unless those batteries are introduced to a circuit. And yet, before you add those batteries to a circuit, a difference in electrical potential exists between the terminals. Therefore, you still have voltage. That doesn’t include situations that involve superconductors which are a special case.
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.
Current and voltage are not the same things. People use those words interchangeably. However, in a circuit, the ‘thing’ that flows is the current. To be more specific, the current is the rate at which an electrical charge flows. The voltage is the ‘thing’ that causes the current to flow.

Current is only present when there is a path for it. That path can be to a grounding point or a grounded point. For example, there''s no current in a lighting circuit until a light is turned on. Once the light is switched on, only current needed to power the light passes through the circuit.
The max current is determined by it''s internal resistance. Many 4.2V lipo batteries can supply much more current than 9V batteries since they tend have lower internal resistances. That being said, the maximum current …

The max current is determined by it''s internal resistance. Many 4.2V lipo batteries can supply much more current than 9V batteries since they tend have lower internal resistances. That being said, the maximum current you can safely draw from a battery is often related to its capacity (see C ratings), but this varies battery to battery ...

Now it''s reading around 49 volts, but there is no current. As soon as I turn the display on it drops to zero volts and shuts off. Does anyone know what is causing this? How …
Now it''s reading around 49 volts, but there is no current. As soon as I turn the display on it drops to zero volts and shuts off. Does anyone know what is causing this? How can there be voltage but no current?
No, a battery cannot function with voltage but no amps. Amps, or amperes, represent the flow of electric current, which is essential for a battery to perform work. The …
Most batteries will still show a voltage across their terminals when discharged but it drops away as soon as you try to draw current from it. A charged battery will sustain the …

Despite the lack of voltage output, there is still a current flowing through the circuit. This is due to the small amount of resistance in the shorting wire and the overall …
Most batteries will still show a voltage across their terminals when discharged but it drops away as soon as you try to draw current from it. A charged battery will sustain the voltage under load. if you want a better representation of how much charge there is, you have to measure the voltage while at the same time drawing current.
No, a battery cannot function with voltage but no amps. Amps, or amperes, represent the flow of electric current, which is essential for a battery to perform work. The presence of voltage indicates that there is an electric potential available. However, without current flow, there is no active power to drive a device.
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.
Despite the lack of voltage output, there is still a current flowing through the circuit. This is due to the small amount of resistance in the shorting wire and the overall voltage being determined by the source EMF of the battery or power supply.
