Question

Exercise 24.5 Part A What is the charge on each plato? A parallol plate capactor with crcular plates and capacilance of 10.3 aF is connected to a battlery which peovides a votage of 10 7 V Submit Part B How much would be on the plates if thoir separation were doubled whle the capeacitor remained connected to the battery Submit My Answers Give Up Part C How much charge would be on the plees f he capecor were connded to the baltory afe the radius of without changing theer soparation? Submit MWy Answers Give Up

Explanation / Answer

A parallel-plate capacitor with circular plates and a capacitance = C = 10.3 uF

Voltage = V = 10.7 V.

Charge = q = CV =10.3*10-6*10.7

The charge on each plate =1.1021*10-4 C

B) If their separation were doubled ,capacity is halved but voltage remains same as the capacitor remained connected to the battery
The charge on each plate is halved

The charge on each plate =5.505*10-5 C

C) If the capacitor were connected to the battery after the radius of each plate was doubled without changing their separation, capacity is four times
The charge on each plate =4.4084*10-4 C
