Question

Given a 1.90 μF capacitor, a 1.60 μF capacitor, and a 1.70V battery, find the equivalent capacitance and charge on each capacitor if you connect them. (a) Find the charge on the 1.90 μF when these two are connected in parallel across the battery. (b) Find the charge on the 1.60 μF when these two are connected in parallel across the battery.

Answer 1

Given the two capacitors
   
a)
  When the two capacitors are connected in parallel, the equivalent capacitance is given by
  
   
And given the voltage of the battery
     
the charge on the capacitor is given by
  
   

b)
  When the two capacitors are connected in parallel,
the charge on the capacitor is given by
