There is no formula it depends on the device. If the device is linear it can be ascertain but if it a non linear then it becomes quite complex

What is current capacity?
It refers to a device any device whereby the device has limit to carry current. Therefore the term current capacity
Is BJT is a current control device or voltage control device?
transistor is a current controlled device. as the current flows through the base of the transistor , it works like a close switch.
Is thyristor a current controlled or voltage control device?
Triac is the current control device.
How do you wire a 2V LED to run on 12V?
Light Emitting Diodes (LED) solid state devices are current dependant. LED have ratings for the max current allowed to the LED device. A typical current allowed to a LED is 20ma. Ohms Law is used to determine the resistance required to limit the current to your desired current. The formula is used in this manner: E=12VOLTS the desired current is I = 20ma. R = E/I = 600 ohms. Where E=2 volts dc and I=20ma R= E/I = 100 Ohms.
Is scr current controlled device?
yes it is current controlled
How do you spell ammpmeter?
The correct spelling is "ammeter" (electrical device to measure current).
What is starting current?
A starting current is the first current and power produced by a machines engine or electrical device. The starting current is used to determine the engines natural strength.
How do you spell switch?
Switch is the correct spelling (a change, a device to turn electric current on or off).
Acronym for device that provides an electrical current to correct a patient's heart rate?
AED automated external defibrillator
Can i use pir device on extraction fan?
If the device is the correct voltage, can handle the current (and I mean surge starting current, not running current. Significant difference), and doesn't mind an inductive load (Get one for a light with a transformer in it (Soduim arc, mercury arc)) it should be fine.
What is current capacity?
It refers to a device any device whereby the device has limit to carry current. Therefore the term current capacity
Is BJT is a current control device or voltage control device?
transistor is a current controlled device. as the current flows through the base of the transistor , it works like a close switch.
How do you spell inverter in UK English?
Inverter is the correct spelling if you are referring to a device that converts direct current to alternating current.Invertor is the correct spelling if you are referring to a muscle in the body that turns a limb.
Is thyristor a current controlled or voltage control device?
Triac is the current control device.
On what factors the current flowing through a device depends?
Current flowing through a device depends on resistance offered by that device.
How to determine the correct fuse for your head unit if you do not know the correct amplitude of the fuse how to calculate?
You would need to know the weakest point in the power distribution and you'd need to know the peak and nominal current draw in Amperes. If it's a device that uses a surge of current at startup but only a fraction of that during normal operation, you would need a "slow-blow" fuse. If the current draw is consistent you would need a conventional fuse. Still have no idea what the "head unit" is that you're trying to fuse.
How do you determine the amount of electrical energy used by a device?
Measure the current flowing through the device and the voltage across it; multiply the current by the voltage to get the power in Watts. Watts = Volts x Amps ; Watts = Amps2 x Resistance (steady state answers using friendly units)
