Why electrons move opposite to electric field? But when the electron was discovered, the scientists found that electron move from -ve to +ve terminal outside te battery or cell. Some resistors, such as carbon based, produce more noise. Theelectric fielddirection within a circuit is by definition the direction that positive test charges are pushed. Due to the changing magnetic field (ie, the wire becomes an inductor) high frequency AC signals typically travel near the surface of the wire. Pote Moving in One Direction What was the amount of additional wor If the poles of a voltage source are joined by a conductor, the free electrons within that conductor will drift toward the positive pole (electrons having a negative charge, opposite charges attracting one another).
