Engineers use alternating current (AC) electronic loads to test electronic applications that require linear or nonlinear AC loading. AC electronic loads have features such as constant current, resistance, voltage, and power, as well as short circuit protection capabilities. AC electronic loads test equipment and take measurements such as frequency, voltage, current, power, and resistance. AC electronic loads give engineers the ability to make measurements internally.
