AC voltage varies periodically while DC voltage remains constant.
Ohm's law states that the current flowing through a conductor between two points is directly proportional to the potential difference or voltage applied across the two points, as long as other factors affecting resistance remain constant.
Ohm's law states that the voltage (V) across a component is equal to the product of its resistance (R) and the current (I) passing through it.
AC can be transformed to higher or lower voltage using transformers but DC cannot.
A series circuit has only one pathway for electricity, while a parallel circuit has multiple paths for electricity.
AC current reverses direction periodically while DC current flows in only one direction.
