Direct and Alternating Current

4.5 2 Reviews SKU: ELACDC0CENDuration: 60 Minutes

Most electric power is generated and consumed in the form of alternating current (AC), and most meters that measure energy consumption are designed to measure AC power. Many of the principles associated with direct current (DC) circuits also apply to AC circuits. This course describes variations that account for differences between DC power and AC power.
