electricity
Electrons in every part of the circuit begin to drift under the influence of this electric field and a current begins to flow in the circuit immediately. You have to note here that if the potential difference you''re applying is constant as with a D.C battery the electric field remains constant, and thus the current remains constant.

Doesn''t a battery provide a current source since and since is constant
Similarly, an ideal voltage source provides a constant voltage no matter what you attach to it. If you change, the battery (which provides constant no matter what is) will give you a different current. A battery is a voltage source, not a current source. Some terminology: what you attach across a source is often referred to as a ``load

What is considered acceptable constant current draw on a vehicle?
2 天之前· That''s a good sign the battery is healthy. A weakening battery will have lower and lower resting voltages. 12.5, 12.4, 12.3, 12.2 - and at this point I start worrying about a battery. 12.1, 12.0 and confidence is low. 11.9 resting voltage - yeah, it''s time for a new battery.

Why is current the same in a series circuit?
The energy inside a battery could accelerate electrons to a very high velocity. However, this doesn''t happen in a circuit. Just as the battery speeds up an electron, the electron hits to another one and remains constant speed. So the battery constantly pushes the electron but in the end it comes back to it with the same velocity. It''s like

What is a constant current battery?
Constant current is a simple form of charging batteries, with the current level set at approximately 10% of the maximum battery rating. Charge times are relatively long with the disadvantage that the battery may overheat if it is over-charged, leading to premature battery replacement. This method is suitable for Ni-MH type of batteries.
What is constant current & constant voltage?
Constant current is a simple form of charging batteries, with the current level set at approximately 10% of the maximum battery rating. Constant current/constant voltage is a combination of the above two methods. The charger limits the amount of current to a pre-set level until the battery reaches a pre-set voltage level.
What is constant current (CC) charging?
Constant current (CC) charging initially allows the full current of the charger during the BULK stage to flow into the battery regardless of the battery state of charge or the temperature until the battery terminal voltage reaches a pre-set steady state. The battery is now in a state of charge of >80%.
Is a Norton battery a constant current source?

What is a constant current source?
A constant current (CC) source supplies a steady current, regardless of the load resistance or voltage drop across the load. This means that the current remains fixed even if the load changes. A CC source automatically adjusts its voltage to ensure that the current remains at the set value.
What is constant voltage & how does it work?
Constant voltage allows the full current of the charger to flow into the battery until the power supply reaches its pre-set voltage. The current will then taper down to a minimum value once that voltage level is reached.
