Physics · Class 12 · CBSE — Alternating Current
An alternating current is given by \({I}={I}_{0} \cos (100 \pi) {t}\) . The least time the current takes to decrease from its maximum value to zero will be:
- \(\left(\frac{1}{200}\right) {s}\)
- \(\left(\frac{1}{150}\right) {s}\)
- \(\left(\frac{1}{100}\right) {s}\)
- \(\left(\frac{1}{50}\right) {s}\)
Answer
(A) ( 1 200 ) s
