power-supply voltage current theory
$begingroup$ I suspect they themselves don''t quite know what they mean by ''drawing'' current. However, a "load" is essentially a device to which power is delivered.Thus, increasing the load on, e.g, a motor, requires the motor to deliver more power and, assuming the voltage to the motor is (more or less) constant, this means an increase in current through the …
How Much Current Does It Take To Burn Out An LED? | Science …
LEDs light up when electrical current flows through them. To get current to flow through an electrical circuit, you need to apply a voltage (measured in volts (V)) from a power supply like a battery or a wall adapter (like a phone charger).However, you have to be careful because the LED will burn out if too much current flows through it. Electrical current is measured in …

First, the diode blocks electric current from one side, allowing only DC current to move out. If the battery is in an inverted position, the ground current will flow from behind the diode, which will not block anything as it is in reverse. With the starter button on, there is a high risk of the diode burning as the current flows with no load.

Inrush Current. On DC solenoids, inrush current is the same value as holding current. Therefore, some of the burn-out conditions previously described may not apply. Fast Cycling. Because of the low inrush current, DC solenoid valves can usually be cycled at higher rates than AC solenoid valves without overheating and coil burn-out. Repeatability.
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.

Laptop power supplies, does current matter?
The difference in current has to do with how fast it can charge the battery. Higher capacity batteries take longer to charge, and a beefier power supply can supply more current to the battery to charge it faster. The thing about charging a battery is that the charge/discharge cycle wears the battery out. The faster you charge it, the faster the ...
What causes a fuse to blow, the current or the power?
The fuse blows when it get too much energy. That is watts x time. If the energy in IR^2 x time is higher than it can dissipate, then it heats up and eventually blows. Time is critical. A 1 amp fuse can withstand a 100 amp pulse, provided it is short. See fuse tables. Similarly a 1 amp diode can can take many more amps provided it is short.
Will fitting a physically bigger battery reduce the working life of the ...
The battery doesn''t ask the alternator for more current. The alternator is rated to provide a fixed amount of current and the battery (or voltage/charge regulator) just takes it. You can charge a battery with 1A, 0.123A, or 10A. The less A the longer it takes. The charge voltage will always be a bit over 12V, around 13-15V. P=IxV, and V is fixed.
Are too high capacitance capacitors "bad" for the circuit?

Phone chargers are designed for specific voltage and current outputs, which may not match the ...
Electrical Current Explained
If we use a 100 ohm resistor, then the current would be 0.09 amps, which is too much. And the LED will burn out. If we use a 450 ohm resistor than the current is 0.02 amps, which is below the limit. So that should be OK. If we use a 900 ohm resistor, then the current is 0.01 amps, which is far too low, so the LED will not shine brightly. Fuses
What happens if I put a higher amp battery in my car?
On the other hand, the capacity of a battery, which is measured in Ah, represents the amount of electricity that a battery can provide. The more capacity (Ah) a battery has, the more electricity it can provide. In theory, a battery that has 100Ah could give a current intensity of 100 Amps for 1 hour, an intensity of 1 Ampere for 100 hours, or 2 ...
