240 volts is a measure of electrical potential difference, commonly used in residential and commercial power systems. It is higher than the standard 120 volts found in many homes, allowing for more efficient operation of heavy-duty appliances like electric dryers and air conditioners.
In regions like Europe and Australia, 240 volts is the standard voltage for household electricity. This higher voltage can deliver more power with less current, reducing energy loss in wires. However, it also requires proper safety measures, as higher voltages can pose greater risks of electric shock.
