A research scientist is studying the effects of electromagnetic fields on the human brain. She observes an increase in the amplitude of the AC signal over time. What is the likely cause of this phenomenon?
Q1. A research scientist is studying the effects of electromagnetic fields on the human brain. She observes an increase in the amplitude of the AC signal over time. What is the likely cause of this phenomenon?
Answer: Resonance
Explanation: An increase in amplitude due to resonance would occur when the circuit is tuned to a specific frequency.
