WebIf 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 ... WebJul 20, 2024 · Jun 29, 2024. #2. Charges moving in a magnetic field are subject to a force that moves them. When charges move, potential differences are created. It is a consequence of Maxwell's equations that a changing magnetic field produces an electric field, AND a changing electric field produces a magnetic field. Everything is coupled when …

WebThe current in a circuit is directly proportional to the electric potential difference impressed across its ends and inversely proportional to the total resistance offered by the external circuit. The greater the battery voltage (i.e., electric potential difference), the greater the current. And the greater the resistance, the less the current. WebNov 19, 2024 · Hypothesis: When the current that passes through a metal wire increases, the potential difference across the metal wire increases. Variables: (a) Manipulated variable: …

WebDependent on the source of the electric field, current will adapt to resistive properties to ensure the voltage drop equals the potential difference across the circuit. The potential drop part means that the electrons loose electric potential as they move through the wire. This can also be compared to a gravitational field.
