The flow of electrons from the negative terminal of a source to the positive terminal in a closed circuitAnswer quickly please... |
|
Answer» Conventional CURRENT ASSUMES that current FLOWS out of the positive terminal, through the circuit and into the negative terminal of the source. This was the convention chosen during the discovery of electricity. They were wrong! Electron Flow is what actually happens and ELECTRONS flow out of the negative terminal, through the circuit and into the positive terminal of the source. Both Conventional Current and Electron Flow are used. Many textbooks are available in both formats. plzzz follow me I am a big fan of bts if ur also a big fan of bts follow me ❤ |
