Why \(220 \mathrm{~V}\) AC is more dangerous than \(220 \mathrm{~V}\) DC?
- A The DC attracts
- B Peak voltage for \(\mathrm{AC}\) is much larger
- C The body offers less resistance to AC
- D Due to some other reason
Answer & Solution
Correct Answer
(B) Peak voltage for \(\mathrm{AC}\) is much larger
Step-by-step Solution
Detailed explanation
Rms value of AC, \(V_{\mathrm{rms}}=220 \mathrm{~V}\) Peak value of AC, \(V_0=\sqrt{2} V_{\text {rms }}=\sqrt{2} \times 220=311 \mathrm{~V}\) \(V_{D C}=220 \mathrm{~V}\) Since, peak value of \(220 \mathrm{~V} \mathrm{AC}\) is \(311 \mathrm{~V}\) which is much more than 220 DC.…

The wire is suspended from \(205 \mathrm{~cm}\) high ceiling of a room. When the system is made to oscillate as a simple pendulum, the sphere just grazes the floor at its lowest position. The velocity of the sphere at the lowest position is (Young's modulus of steel \(=2 \times 10^{11} \mathrm{Nm}^{-2}\) and acceleration due to gravity \(=10 \mathrm{~ms}^{-2}\) )AP EAMCET 2018 Hard
