Electric Field and Current Flow in a Wire
Electric Field:
- Electric field is a region around a charged particle or object within which a force would be exerted on other charged particles or objects.
- The direction of electric field is the direction in which a positive charge would move if placed in the electric field.
- Electric field is measured in units of newtons per coulomb (N/C).
Current Flow in a Wire:
- When an electric potential difference is applied across a conductor, a current flows through it.
- The direction of current flow is the direction in which positive charges move.
- Current is measured in units of amperes (A).
Electric Field and Current Flow in a Wire:
- Whenever a current flows in a wire, an electric field is set up around the wire.
- The direction of electric field is the same as that of current flow.
- This is because the electric field is set up by the charges that are moving in the wire.
- If the charges are moving in a particular direction, they set up an electric field in the same direction.
Conclusion:
- Option 'A' is the correct answer as the direction of electric field is same as that of current flow in a wire.
