Thinking about two batteries next to each other, linked by one wire-- there is no voltage between the two batteries, so there is no force to drive electrons. In each battery, the
Does voltage cause current or does current cause voltage?
$begingroup$ Thank you, that was very helpful, but what about all these textbooks that explain so many circuit/device operations through a cause-effect relation between current and voltage? wouldn''t you agree that especially when they explain diodes, regulators, transistors etc they use voltage and current as one causing the other? I still cant help but think

What Size Wire Do I Need for a Battery? A Comprehensive Guide
Understanding Wire Gauge and Current Capacity. The American Wire Gauge (AWG) system is a standardized method of measuring wire thickness. In this system, lower gauge numbers indicate thicker wires, which can carry more current with less resistance. Conversely, higher gauge numbers signify thinner wires, suitable for lower current loads.Selecting the
Whether a battery is a constant voltage source or current source
Thus, when you draw current from the battery, the voltage across the resistor goes up which means the voltage across your circuit goes down. Eventually you deplete the battery. When this happens, we can no longer treat all of the parts of the battery in bulk. Parts of the battery will remain charged, other parts will be fully discharged.
Electric Car Batteries Voltage and Current
Electric cars have two batteries: a high-voltage (rechargeable) battery carrying several hundred volts, and a 12 V starter battery, which is installed in all cars for starting.. In electric cars, such as the ID. models from Volkswagen, two types
Answer all the questions below then check your answers
1. What happens to the voltage when the difference in reactivity between two metals in a simple cell increases? The voltage increases as the difference in reactivity between the two metals increases. b. A simple cell consisting of the two metals copper and zinc dipped into an inert electrolyte produced a voltage of 1.2V. How could the voltage
Why are different currents used for charging batteries with the
A battery charger must produce a voltage a little higher than the battery voltage - how much higher depends on the battery chemistry, temperature, and other things. 1 Amp and 2 Amp chargers for a given battery type will produce the same final voltage, but the 2 Amp charger can deliver a higher currrent into a discharged battery.

You can measure the voltage across a cell or battery close battery A chemical supply of electrical energy. For example, common battery voltages include 1.5 V and 9 V.. The more
batteries
There are many types of BMS (and many definitions of "normal"), but generally, in case of too high a charging current, a BMS will not limit the current to an acceptable level but simply stop the charging, and yes, this does protect the battery, but there will be no charging.
What is Battery Voltage? Why Does It Matter and
If we talk about more differences between the battery voltage and current, voltage is a scalar quantity, which means it has magnitude but no specified direction. On the other hand, current is a vector quantity that has

6 FAQs about [Do batteries carry current or voltage ]
Do batteries have a fixed voltage?
So, as a general rule of thumb, batteries have a fixed voltage but: big or new batteries tend to have a low internal resistance, so they can deliver a high current small or old batteries tend to have a high internal resistance, so they can’t deliver much current This entry was posted in -- By the Physicist, Engineering, Physics.
Does a battery have a voltage difference?
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 positive end" and the "excess electrons on the negative end" - is relative to a given battery.
Why is a battery considered a voltage source?
As the chemistry shifts with discharge (or charge) the no load voltage changes slightly and the internal resistance changes as well. A battery is considered to be a voltage source because the galvanic activity they use to store and deliver energy has a fixed voltage across it. However, a battery is not an ideal voltage source.
Why do batteries with the same voltage have different currents?
Experts say "current depends on voltage". So, if the voltage is high, current would be high. Agreed; (I = V/R) If the voltage is low, the current would also be low. Agreed -> I = V/R
