How an Electric Kettle Works: Heating Process & Convection Explained #3683810 (License: Personal Use)

This diagram illustrates the internal operation of a standard electric kettle: submerged heating elements warm the water, creating upward thermal currents (red arrows) while cooler water descends (blue arrows), establishing convection. Steam escapes through the spout once boiling point is reached, signaling readiness. The transparent body reveals the coiled resistor and lid mechanism for safety and efficiency.
