Yes. Ohm's law is generally thought of as a basic law of electricity, but electricity is, in the language of physics, a part of the electromagnetic force. The electromagnetic force is one of the four basic forces in the universe (allong with gravity, the strong force (called the strong interaction) and the weak force (called the weak interaction). That's the electromagneticforce. Not the electric force or the magnetic force, but the electromagnetic force. And Ohm's law is a most fundamental expression of the relationship of voltage, resistance and current in an electrical circuit. In that light, Ohm's law is a general law of the electromagnetic force. Note: Some science teachers might try to split hairs here and say that Ohm's law is an electrical law and not an electromagnetic law, but this is one of those questions that might be said to have two answers. As regards what was said in the first paragraph, nothing in it is incorrect. Nothing at all.
Another Answer
Absolutely NOT! For Ohm's Law to be valid, the ratio of a circuit's voltage to current must be constant for variations in voltage. In other words, if you were to plot current against voltage for variations in voltage, you should end up with a straight-line graph. In fact, this is rarely the case. In most cases, you will end up with a curved line which confirms Ohm's Law does NOT apply.
Most materials and electronic devices (diodes, etc.) are classified as being 'non linear' or 'non-ohmic', meaning they DO NOT OBEY OHM'S LAW.
So Ohm's Law is most certainly NOT a universal law and, in fact, barely qualifies as being a law at all!
ohms law.
no
No.
in transformer
Using Ohms Law, the answer is 120/0.5 = 240 Ohms.
ohms law.
To find the conductance using ohms law,you take the inverse of the resistance(/R)
Current
No.
no
ohms=amps/volts Amps= volts/ohms Volts = Amps*Ohms
Ohms law does not consider inductance
Ohms law.
in transformer
no
The mathematical form of Ohms law is I=V divided by R. I is current, V is voltage while R is the resistance.
Ohm's Law is unrelated to power.
