Which phenomenon maximizes power transfer to a microwave oven's water load when operating at 2.45 GHz?

💡 Explanation

When a microwave oven operates at 2.45 GHz, dielectric relaxation of water molecules occurs because this frequency matches the rotational resonance of water, leading to efficient energy absorption and heating. Therefore, dielectric relaxation maximizes the power transfer, rather than interference, inherent frequency, or cage effects which operate through different physical mechanisms.
