COMEDK · Physics · 23. Alternating Current
\(220 \mathrm{~V}\) ac is more dangerous than \(220 \mathrm{~V}\) dc Why?
- A The speed of ac is more than that of \(\mathrm{dc}\)
- B Shock received from ac is always repulsive
- C The frequency of ac is more than that of dc
- D The peak value of ac is greater than the given value of dc
Answer & Solution
Correct Answer
(D) The peak value of ac is greater than the given value of dc
Step-by-step Solution
Detailed explanation
The voltage specified for an alternating current (ac) circuit, such as \(220 \mathrm{~V}\), refers to the root mean square (rms) value, denoted as \(V_{rms}\). The relationship between the peak value (\(V_0\)) and the rms value for a sinusoidal ac voltage is given by…
