28、In physics, one of the well-known laws is Ohm's law, on the basis of this law we can know the relation of the current,the voltage and the resistance . ─── 在物理学中,一个众所周知的定律叫欧姆定律,根据这个定律我们可以知道电流,电压和电阻之间存在的关系。 29、Koss 60 ohm: Sounds...
physics Print Also known as: Ohm’s law of electrical resistance Written and fact-checked by The Editors of Encyclopaedia Britannica Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or ...
is one of the fundamentals of electrical engineering, at the time of publication it was received with criticism. The ohm is adopted as the official SI unit for electrical resistance. Gustav Kirchhoff (known fromKirchhoff’s circuit laws) made a generalization that is used more often in physics:...
This is kind of like the F equals MA of physics 2. So definitely commit V equals IR to memory because you're going to be using it a lot in the future. Alright, guys. That's basically it. That's the equation that you need to know. Let's go ahead and work out some practice ...

What causes the current to flow through the whole circuit in the given example? I understand that on the disk there is an emf (integral of force per unit charge) from the centre of the disk to the edge (00 to aa) but unlike a stationary circuit with a battery, where you have an in...
