Question

Choose the correct statement from the following.

• A. Electric current is a scalar quantity.
• B. Charge carriers in metals are ions.
• C. The area of current - time graph gives charge.
• D. A charge in motion produces both electric and magnetic field.

Answer 1

Answer: (A), (C), (D)

Electric current is a scalar quantity.
The area of current - time graph gives charge.
A charge in motion produces both electric and magnetic field.

Electric current is a scalar quantity. Charge carries in metals are electrons. The area of current-time graph gives charge. A charge in motion produces both electric and magnetic field.
