Does Ohm's Law still apply when the total number of Amps is limited?

In summary, Ohm's Law is a fundamental principle in the study of electricity which states that the current through a conductor is directly proportional to the voltage and inversely proportional to the resistance. It still applies even when the total number of Amps is limited and can be used to calculate voltage or resistance when the current is limited. It is essential in understanding circuits and can be applied to both AC and DC circuits, although calculations may be more complex in AC circuits due to the presence of impedance.

As in, what if you have a VERY high voltage? Then I = V/R.

But what if you only have a limited number of charge carriers that could eventually run out? Then what will happen to the current? Will it suddenly stop following Ohm's Law? Will it immediately drop off to 0, or gradually drop off to 0?

You can't have high voltage without enough charge being separated, so when you run out of charge carriers, you run out of high voltage as well.

Oh okay. That resolves the conundrum!
 

1. What is Ohm's Law?

Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them.

2. Does Ohm's Law still apply when the total number of Amps is limited?

Yes, Ohm's Law still applies when the total number of Amps is limited. The limitation of amps does not affect the relationship between voltage, current, and resistance.

3. Can Ohm's Law be used to calculate the voltage or resistance when the current is limited?

Yes, Ohm's Law can be used to calculate the voltage or resistance when the current is limited. As long as two of the variables (voltage, current, and resistance) are known, the third can be calculated using Ohm's Law.

4. How does Ohm's Law relate to the concept of a circuit?

Ohm's Law is a fundamental principle in the study of electricity and is essential in understanding how circuits work. It helps explain the relationship between voltage, current, and resistance in a circuit.

5. Can Ohm's Law be applied to both AC and DC circuits?

Yes, Ohm's Law can be applied to both AC (alternating current) and DC (direct current) circuits. However, in AC circuits, the calculations may be more complex due to the presence of impedance, which includes both resistance and reactance.
