The antenna current of an AM transmitter is 8 A, when only the carrier is sent, but it increases to 8.93 A when the carrier is modulated by a single sine wave. Determine the antenna current when the percent of modulation changes to 0.8

Q: The antenna current of an AM transmitter is 8 A, when only the carrier is sent, but it increases to 8.93 A when the carrier is modulated by a single sine wave. Determine the antenna current when the percent of modulation changes to 0.8

Ic = 8 A m = 0.8 = 8 x 1.149 = 9.19 A.

9.19 A
9.91 A
10.56 A
8.61 A

Correct Answer: 9.19 A

Explanation:

I_c = 8 A

m = 0.8

= 8 x 1.149 = 9.19 A.
