what came first, electrical appliances or electric theory?
Electric theory came before electrical appliances. The development of electric theory can be traced back to the 17th and 18th centuries when scientists like Benjamin Franklin, Charles-Augustin de Coulomb, and Alessandro Volta conducted experiments and made important discoveries about electricity. They formulated theories and principles regarding the behavior and properties of electricity, such as Franklin's experiments with lightning and his theory of positive and negative charges.
The practical application of electric theory in the form of electrical appliances came later. In the late 19th and early 20th centuries, inventors and engineers like Thomas Edison and Nikola Tesla made significant contributions to the development of electrical appliances and power systems. They harnessed the understanding of electric theory to create devices such as light bulbs, telegraphs, electric motors, and generators, which eventually led to the establishment of electrical power grids and the widespread use of electrical appliances.
