TS EAMCET · Physics · Alternating Current
An current is given by the expression, in amperes. The frequency and RMS value of the current respectively are
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Standard equation of the current variation in an AC supply can be written as, I=I0sinωt, where I0=peak current and ω=angular frequency. Comparing it with the given expression of current, we get I0=50 A. Therefore, RMS current IRMS=I02=252 A Similarly,…
