Question

An alternating voltage of frequency ⍵ is induced
in electric circuit consisting of an inductance L
and capacitance C, connected in parallel. Then
across the inductance coil the
(i) current is maximum when ⍵² = 1/(L C)
(ii) current is minimum when ⍵² = 1/(L C)
(iii) voltage is minimum when ⍵² = 1/(L C)
(iv) voltage is maximum when ⍵² = 1/(L C)
State if
(a) if (i) and (iii) are both correct
(b) if (i) and (iv) are both correct
(c) if (ii) and (iii) are both correct
(d) if (ii) and (iv) are both correct

Answer 1

Answer:

In parallel LC currents, current is minimum when, Omega = whole root 1/ LC

Also, current and voltage are at angle of 90 degrees

Hence, Voltage is maximum when current is minimum

Hence, option D is correct...

Hope it helps...✌️✌️✌️
