Alternating current changes direction periodically. ω=2 π v and ε=ε0 sin 2 π v t

Q. Statement I The direction of the current changes periodically and therefore the current is called alternating current.
Statement II Equation $ε = ε_{0} sin ω t$ can be written as $ε = ε_{0} sin 2 π v t$

Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I.
