Answer 1

$\huge\mathbb{\orange{QUESTION-}}$

What would be the frequency of an alternating current if its direction changes after every 0.01 second.

$\huge\mathbb{\orange{SOLUTION-}}$

$\large\underline{\underline{\sf Given:}}$

• Current if its direction changes after every 0.01 second

$\large\underline{\underline{\sf To\:Find:}}$

• What would be the frequency (f)

$\large\underline{\underline{\sf Formula\:Used:}}$

❏$\large{\boxed{\sf Time(T)=\dfrac{1}{f} }}$

${\sf Time\: period\: is \; the \:time\: required \:to \: Complete }$

${\sf one\:cycle }$

⛬ Time period of the Current is ⎯

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 2 × 0.01

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 0.02 second

$\implies{\sf \blue{ f =\dfrac{1}{time\:period}} }$

$\implies{\sf f = \dfrac{1}{0.02}}$

$\implies{\bf \red{ f = 50\:Hz }}$

$\huge\mathbb{\orange{ANSWER-}}$

${\bf \red{50\:Hz}}$ the frequency of an alternating current if its direction changes after every 0.01 second
