|In 1834, a clockmaker named Jean Charles Peltier found that if you take two wires of dissimilar metals and apply an electric current, there will be a change in temperature at the junction of the wires. Depending on the direction of the current, the temperature will either rise or fall. One practical outcome of this discovery is a small solid-state heat pump used for semiconductors that’s known as a thermoelectric cooler.|
Today’s Word of the Day is thermoelectric cooling.
