AC and DC Voltage

AC voltage it’s a short cut from Alternating Current is an electrical current which has two signals Negative and Positive. We use it in electricity and some electronic equipment such as Power Supply, Functional Generator. See the sin wave of the AC voltage below.


DC voltage is the short cut of Direct Current it has only one signal Positive or Negative.
You can find it in a cell battery, solar cells or dynamos. See the sin wave of the DC voltage below.
