Power''s relationship to Resistance
A way of visualize this is think of a constant voltage source (i.e. a battery). When there''s a large resistance connected, very little current can flow so very little power is being outputted by the battery, and the resistor won''t get too warm because there''s less power.
Maximum current draw from 12v sealed lead acid battery?
Even at 8A, the battery will be flat after half an hour. And be aware that lead-acid batteries don''t like being left flat. Once run down, they should be recharged as soon as possible, or they may be permanently damaged. *1C is a current numerically equal to the amp-hour rating of a battery. So for an 8Ah battery, 1C is 8A.

How do battery chargers work?
In taper-current charging, the charger starts off using a high, constant current, which progressively lowers to a trickle as the battery fills with charge and reaches its peak voltage. Inexpensive chargers often work this way. Two alternative ways of charging are constant current (CC) and constant voltage (CV).

batteries
Le''s assume the load resistance is 4.5ohm and battery voltage is 9v, so current flow through the loop is 2amp; for the same load resistance(not be changed in any variation of voltage and current), if the battery voltage is 18v the current flow through the loop becomes 18v/4.5ohm=4amp. if I am wrong please give me feed back.
Understanding Alternator Power Output | HowStuffWorks
As Nikola Tesla proved in 1887, alternating current becomes more attractive as it generates higher voltage more efficiently, something necessary in contemporary automobiles.But car batteries can''t use AC power since they produce DC power. As a result, the alternator''s power output is fed through diodes, which convert …

Direct current
A direct current circuit is an electrical circuit that consists of any combination of constant voltage sources, constant current sources, and resistors. In this case, the circuit voltages and currents are independent of time. A particular circuit voltage or current does not depend on the past value of any circuit voltage or current.
A Guide to Understanding Battery Specifications
maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power.
How do I design a constant current load circuit?
Designing a constant current load circuit to discharge a battery? The basic math behind a CC load is well presented here in a TI application note.. In this application a DAC is used to set a precise current value, but of course this could equally be a simple pot across VCC to Ground.
Does a battery charger limit current?
The input current draw is dictated by the output load (voltage output and current draw of output) and efficiency of the converter. The charging current will be set by the charger depending on battery chemistry and charge time. This sets charge rate which sets the charging current.
10.2: Electromotive Force
Introduction to Electromotive Force. Voltage has many sources, a few of which are shown in Figure (PageIndex{2}). All such devices create a potential difference and can supply current if connected to a circuit. A special type of potential difference is known as electromotive force (emf).The emf is not a force at all, but the term …
20.5: RC Circuits
Discharging. Discharging a capacitor through a resistor proceeds in a similar fashion, as illustrates. Initially, the current is I 0 =V 0 /R, driven by the initial voltage V 0 on the capacitor. As the voltage decreases, the current and hence the rate of discharge decreases, implying another exponential formula for V.
Whether a battery is a constant voltage source or current source
the battery can, under normal circumstances, be either a Thevenin equivalent or a Norton equivalent. in the Thevenin model the battery is a constant voltage source in series with the internal resistance. in the Norton model the battery is a constant current source in parallel with the internal resistance.
