Initially the switch is in position 2 when charging of the capacitor starts. Initially the capacitor was uncharged. The switch in circuit shifts automatically from 2 to 1 when VC>2V/3 and goes back to 2 from 1 when VC<V/3. The ideal voltmeter reads voltage across capacitor as plotted. What is the period T of the wave from in terms of R and C ?

AB is a uniform wire. Then value of 'x' must be : In a practical wheat stone bridge circuit as shown then ratio l1/l2 become '2'l1 is balance length when one more resistance of 100Ω is connected in parallel with unknown resistance 'x'
