🔍 Key Concepts

• Amplitude modulation (AM) and how modulation affects carrier current or power • Relationship between unmodulated carrier current and modulated carrier current for a single sinusoidal tone at 100% modulation • How percentage increase is calculated: increase in current divided by original current, expressed as a percentage

💭 Think About

• First, think about what stays constant in a standard AM transmitter: is it carrier frequency, carrier power, or something else? Then consider how the sidebands affect total power/current at 100% modulation. • Ask yourself: in single‑tone 100% AM, by what factor does total power change compared to the unmodulated carrier? From that, how would the antenna current change? • Once you know the ratio between modulated and unmodulated antenna current, apply that ratio to 8 A and see which option (if any) matches.

✅ Before You Answer

• Be clear on whether the given 8 A is the unmodulated carrier current or the current after modulation. • Double‑check how to convert from a power ratio to a current ratio (remember: power is proportional to current squared for a fixed load). • After you compute the new current, verify whether the numerical value matches 9.8 A and whether the percentage increase matches 22.5%; see if both, one, or neither are correct.
