WebbElectric current is a flow of electric charge. Charge can be positive (protons) or negative (electrons), and both types of charged particles can and do flow in electric circuits: In metal wires, carbon resistors, and vacuum tubes, electric current consists of a flow of electrons. WebbIn certain types of materials, particularly liquids and plasmas, current flow is a combination of both electrons and ions. Figure 8 shows the simplified drawing of a voltage cell. All cells consist of two electrodes of different materials immersed in a …

WebbThese are proton-conductor solids, designed for large proton currents without any damaging breakdowns required. Car-battery's acid is mostly a proton conductor, since the acid's +H ions have far higher mobility than the equal … Webb9 mars 2024 · This is often remembered as: Quantity of charge Q = current I x time t Q = It Where: Q = quantity of charge in coulombs, C I = current in amperes, A t = time in … contact factors
Why is the charge transferred by electrons and not by protons?
Webb21 mars 2024 · If a current of 1A flows through a copper wire, the number of electrons flowing by a cross section of the wire in 1s is equal to : 1A=(1C/1s)(electron/-1.602*10^ … WebbYou can totally transfer charge using protons. Or using Na+ or any kind of charged particle. It happens all the time - if you look at how a wet cell battery works, you'll find that while charge across the wire is carried by electrons, current flows along the salt bridge via charged ions (theoretically protons could be among these). I bet if you could somehow … Webb7 maj 2024 · When current flows, electrical work is done and energy transferred. The amount of charge passing a point in the circuit can be calculated using the equation: charge = current × time \ [Q = I... contact factor
