Question

A 15F capacitor is connected to a 50 V battery andbecomes fully charged. The battery is removed and a slab ofdielectric that completely fills the space between the plates isinserted. If the dielectric has a dielectric constant of 5.0, a. What is the capacitance of the capacitor after teh slab isinserted? b. What is the voltage across the capacitor's plates after theslab is inserted? A 15F capacitor is connected to a 50 V battery andbecomes fully charged.

Explanation / Answer

Initially c0=15uF and cvolt=50volt now we know that c=k A/d                                   // c0=15=A/d given k=5so c1=5*50=250uf now votage across capacitor can't change Instantaniously hence c1volt=50volt BEST OF LUCK
