Current flow in batteries?

$begingroup$ Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics. Not noticable at most voltages, but see what happens when you touch a peice of metal to a 100,000kV line, even in a vaccumm with no earth, a sizeable current will flow to bring the metal to the same electrostatic charge.

Is a Car Battery AC or DC Power Source?

AC Battery: Some power sources generate voltage and current in alternating directions that change direction after some time. The AC current advantage over DC current is that the voltage of AC can be transformed into a higher or lower voltage level after some operations, but it is difficult for DC. So in buildings, houses, and offices, AC is used.

Is a Battery AC or DC? Explained in Simple Terms

A battery can be a source of DC power that operates on direct current or AC power that operates on alternating current. The battery is a current source that can supply DC power. However, it is important to note that the battery itself does not generate DC or AC power. It stores chemical energy and converts it into electrical energy, which can

High Current or High Voltage that damages components?

If you then swap that battery to 20V, would it be the new current of 4A that does the damage or that fact that the voltage is now 20V? Both values are higher than they should be so which factor will do the damage, both? 2) Also, if when you swapped to a 20V battery, you also increased the resistance in the circuit to 10 Ohms, could this still damage

From what I understand and from what I''ve read, a 9v battery creates a voltage (potential difference) by doing 9 joules of work (9 joules of chemical energy into 9 joules of electrical potential energy) to pull electrons away from their atoms and their normal state to a point of high potential energy, therefore creating a potential difference

How are current and voltage related to torque and speed of a

After 4 years using and studying electrical vehicles I figured out that "gradeability" (ability to raise a slope of specific grade) depends on motor torque, and torque depends on current. Voltage instead "regulates" how fast a motor can run: the maximum speed a motor can reach is the speed at which the motor generates a voltage (named "Counter

6 FAQs about [Does the battery generate current or voltage ]

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.

Does a current produce a voltage?

@transistor It's not the current that produces a voltage. It's a collapsing magnetic field that creates an electric field which causes the voltage which then causes a current. Let's say I drive by a stationary charge. From my view, it's a moving charge, and therefore a current.

How do you know if a battery is connected to a current source?

if the internal resistance is very low compared to the load, the battery is connected to, looking at it as a Thevenin model (a voltage source) makes more sense. if the internal resistance is very high compared to the load the battery is connected to, looking at it as a Norton model (a current source) makes more sense.

How does a battery work?

The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work. To balance the flow of electrons, charged ions also flow through an electrolyte solution that is in contact with both electrodes.

Is a battery an ideal voltage source?

However, a battery is not an ideal voltage source. All real sources have some built in resistance. In the case of a battery, the effect is well modeled as an ideal voltage source in series with a small resistor (I don't know numbers, but I'd expect it to be single digit ohms).

Does a 12V battery drain more current?

if the internal resistance is very high compared to the load the battery is connected to, looking at it as a Norton model (a current source) makes more sense. It's a constant voltage source, the value of current being drained out of it depends on the load. A 1kw 12v motor will drain more current from the battery than a 0.5 kw 12v.
