Question 6A420

Field intensity, also known as electric field strength (E-field), is a measure of the strength of the electromagnetic wave at a specific point in space. This field is generated by the alternating current flowing in the antenna. The strength of the radiated electric field is directly proportional to the magnitude of the antenna current. This means if you double the current flowing through the antenna, you will double the electric field strength at a given distance. This is a fundamental principle of electromagnetism where the source (current) directly dictates the field it generates. Options B is incorrect because field strength increases with current, not decreases. Options C and D relate to radiated *power*, which is proportional to the square of the current (P = I²R), or derived relationships, not the field intensity itself. The field intensity is linearly dependent on the antenna current.
