Question

Why electrons move opposite to electric field?

Answer 1

because The particles that carry charge through wires in a circuit are mobile electrons. The electric field direction within a circuit is by definition the direction that positive test charges are pushed. Thus, these negatively charged electrons move in the direction opposite theelectric field.

hope it helps

Answer 2

Even before the discovery of the electron the direction of current is taken to be from +ve to -ve terminal outside the battery or cell. But when the electron was discovered, the scientists found that electron move from -ve to +ve terminal outside te battery or cell. Thus, they found that the direction of electric current is opposite to that of the electron flow.
