Question

the equation of an alternating current is I= 10sin200πt. calculate the frequency and r.m.s value of current​

Answer 1

Dear Student,

◆ Answer -

Frequency of A.C. = 100 Hz

RMS value of current = 5√2 A

● Explanation -

Comparing I = 10sin(200πt) with I = I0sin(wt),

I0 = 10 A

w = 200π rad/s

Frequency of A.C. is -

f = w/2π

f = 200π / 2π

f = 100 Hz

RMS value of current is -

Irms = I0/√2

Irms = 10/√2

Irms = 5√2 A

Hope this helps you. Thanks dear for asking..
