The correct answer is option C. insulator.
An insulator material<span> has a high resistivity and prevents the movement of electrons. It is a hindrance in the path of electrons & resists the current flow.
The conductor conducts electrons as it offers very less resistance. A battery provides voltage to the circuit.
Hence, option (c) is correct. </span>
Answer:
The speed is
Explanation:
From the question we are told that
The magnetic field is
The electric field is
Generally the speed of the electron is mathematically represented as
Substituting values
