Some of these reactions can be physically arranged so that the energy given off is in the form of an electric current. These are the type of reactions that occur inside batteries. When a reaction is arranged to produce an electric current as it runs, the arrangement is called an electrochemical cell, a Voltaic Cell, or a Galvanic Cell.
Why Do Citrus Fruits Produce Electricity?
An orange, lemon or lime can act as a battery, and while a single one might not generate enough voltage to illuminate an LED bulb, several wired in series will.

So the C of a 2Ah battery is 2A.The amount of current a battery ''likes'' to have drawn from it is measured in C.The higher the C the more current you can draw from the battery without exhausting it prematurely. Lead acid batteries can have very high C values (10C or …
Why do batteries with the same voltage have different currents?
Current depends on Voltage". So, if the voltage is high, current would be high. Agreed; (I=V/R) True, if you''re asking about resistance. But, you''re asking about a (non-ideal) voltage source - a battery. The voltage to current relationship of a battery depends on the chemistry, temperature, etc. Cells and batteries are not resistors. Now, it is the case that a first approximation of a …

voltage
You can view the voltage as the water pressure in the pipes (high pressure is the equivalent of high voltage). You can view the current as the amount of water which goes through the pipes (high current is the equivalent of a big amount of water). Since we are talking about a battery, this means we are talking about a voltage source.

What is Battery Voltage? Why the Voltage of Your Battery Matters
Batteries generate voltage through a chemical process involving anodes, cathodes, an electrolyte, a separator and a circuit. The circuit serves to connect the anode and the cathode, enabling electrons to move from the anode to the cathode, thus generating voltage. ... By understanding the interplay between voltage, current, and power, you can ...
Do you need high voltage or current to produce a spark?
Before the spark, there is no current at all, only a voltage (potential difference) between two points. Arc discharge happens when the voltage is high enough to overcome the gap, and then continues when conductors are drawn apart until the plasma dissipates. This depends on how large the gap is; you can easily draw visible sparks from a 12V power supply …

For the current to flow in the opposite direction such a potential difference must be higher than the battery voltage at no load. So the voltage at no load, that you are saying in your case is of 9V, is the exact voltage across the battery that is not able to let a current flow in either direction.
