WebEither moving a wire through a magnetic field or (equivalently) changing the strength of the magnetic field over time can cause a current to flow. How is this described? There are two key laws that describe electromagnetic induction: Faraday's law, due to 19ᵗʰ century physicist Michael Faraday. dwdm in telecomWebIf the potential of the plate A is made negative, the photocurrent does not immediately drop to zero but flows in the same direction as for positive potential. This shows that the photo electrons are emitted from the plate C with finite velocity. If the negative or retarding potential is further increased, the photo current decreases and ... crystal gas fires ukWebDec 15, 2024 · Electric potential is defined as the work done to bring a unit positive charge from infinity to that point in the electric field.
