What happens when a source cannot supply enough current?
For example, if I have a source that can supply 1 V and 1 A and I attach it to a resistor that is 0.5 ohms, the circuit will try to draw 2 A but my source is only rated to supply 1 A. What happens here? Would the source supply the maximum rated current of 1 A and only be able to output 0.5V ? Or would the source begin to overheat?

How does supplying a DC motor with lower than rated voltage
$begingroup$ Assuming the 12V coils of the relays are powered from the same battery as the motor, then I''d say that the battery voltage is dropping drastically when the motor starts. In other words: The battery is too weak. You can thank your weak battery for not delivering enough current to kill your relay. $endgroup$ –

power-supply voltage current theory
$begingroup$ If you are asking about motors rather than the term "draw", the resistance does not change under load but something called the back-EMF does. The back EMF of a freely spinning motor will cause the current to be at its minimum. The back-EMF disappears when the motor is stalled and you are left with the resistance of the windings which is relatively

What are the tolerances for the maximum current a battery can supply?
After a lot of research and experimentation I have come to learn that the sentence "This is a 1.5 V, 2800 mAh battery" is entirely a lie. (i.e., the potential difference between the terminals of a battery changes over time and the shape of the graph is dependent on battery chemistry, ambient temperature and current draw, as is the useful energy capacity.

I am looking at a configuration of 16 LiFePo4 cells each in series, each 200 Ah rated at 1 C. At that rated capacity, it would seem the most power I could draw is half that, or 9.6 kW which means a lot of unused power to the engine. If that is correct, the 200 Ah cells must be 2 C rated to make use of the 20 kW of power. Is that correct?

View more6 FAQs about [Does the battery supply rated current ]
Do batteries need a lot of current?
If you only need the battery for a short period of time, it won’t need to supply as much current as if you were going to be using it for an extended period of time. Finally, you need to consider the temperature. Batteries perform better in cooler temperatures and can supply more current in those conditions.
How much current can a battery supply?
A battery can supply a current as high as its capacity rating. For example, a 1,000 mAh (1 Ah) battery can theoretically supply 1 A for one hour or 2 A for half an hour. The amount of current that a battery actually supplies depends on how quickly the device uses up the charge. What Factors Affect How Much Current a Battery Can Supply?
Should a voltage power supply be rated for more current?
However, it is ok to have a voltage power supply rated for more current than the components rated value because the component will draw as much as it needs. If you are pushing more current into (forcefully) the component, then the component will exceed its rated value, heat up and be destroyed.
What determines the amount of current a battery can supply?
The amount of current a battery can supply is determined by several factors. The first factor is the battery’s voltage. This is the potential difference between the positive and negative terminals of the battery, and it determines how much power the battery can supply. The higher the voltage, the more current the battery can supply.
What are the different types of battery ratings?
There are three types of battery ratings: cold cranking amps (CCA), reserve capacity (RC), and amp-hours (Ah). CCA is the amount of current a battery can deliver for 30 seconds at 0°F (-18°C) before its voltage drops below 7.2 volts.
What is a mAH rated battery?
Current is the rate at which electric charge passes through a circuit, and is measured in amperes. Batteries are rated in amp-hours, or, in the case of smaller household batteries, milliamp-hours (mAH). A typical household cell rated at 500 milliamp-hours should be able to supply 500 milliamps of current to the load for one hour.
