when one more resistance of 100Ω is connected in parallel with unknown resistance ‘x’
Sahay Sir > Question Answers > when one more resistance of 100Ω is connected in parallel with unknown resistance 'x'
VC is the ideal voltmeter in the figure. Resistance of the resistor shown is R. 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 ?

A potentiometer wire AB as shown in 40 cm long of resistance 50Ω/m free end of an ideal galvanometer is touching the potentiometer wire with the help of a jockey. What should be the velocity of the jockey as a function of time so that potential difference across the galvanometer is varying with time as (2sinπt)V
