A capacitor with C = 1.50-10^-5 F is connected as shown in the figure to a resistor R = 980 0 and a source of emf. with & = 18.0 V and negligible internal resistance.
Initially the capacitoris uncharged andswitch S is in position1. Then the switch ismoved to position 2so that the capacitorbegins to charge.When the switch hasbeen in position 2 for10.0 ms, it is broughtback to position 1 sothat the capacitorbegins to discharge.
Initially the capacitor
is uncharged and
switch S is in position
1. Then the switch is
moved to position 2
so that the capacitor
begins to charge.
When the switch has
been in position 2 for
10.0 ms, it is brought
back to position 1 so
that the capacitor
begins to discharge.
Calculate:a) The charge of thecapacitor.b) The potentialdifference betweenthe ends of theresistor and thecapacitor just beforethe switch is movedfrom position 2 toposition 1 again.
Calculate:
a) The charge of the
capacitor.
b) The potential
difference between
the ends of the
resistor and the
capacitor just before
the switch is moved
from position 2 to
position 1 again.
c) The potentialdifference betweenthe ends of theresistor and thecapacitorimmediately after theswitch is broughtback from position 2to position 1.d) The charge of thecapacitor 10.0 msafter the switch isreturned fromposition 2 to position1.
c) The potential
difference between
the ends of the
resistor and the
capacitor
immediately after the
switch is brought
back from position 2
to position 1.
d) The charge of the
capacitor 10.0 ms
after the switch is
returned from
position 2 to position
1.
