Question
A parallel plate capacitor has a capacitance of C-1.0 nF and a charge of magnitude 0.20 nC. The plates are 1.0 mm apar a) What is the potential difference between plates? (0.20 V) b) What is the area of each plate? (0.11 m2) c) What is the electric field between the plates? (200 V/m) What is d) capacitance (2.1 nF) and e) maximum voltage which can be applied to that capacitor if the space between the parallel plates is filled with insulator with dielectric constant 2.1 and dialectic strength 60 x 100 V/m? (60 x 103 v) Two capacitors with C-5.0uF and C-2.0uF are connected to a potential difference of V-10.oV. a) Find the charge and potent difference for each capacitor when they are connected in parallel. (for C1:50 HC and 10V; for C:20 uC and 10V) (b) How much energy is stored into both capacitors? (350 pJ) 10V; for Ci : 20 C and 10V)(b) How A 2.00 F capacitor is charged by being connected across a 5.00 V battery. It is then disconnected from the battery and connected across an uncharged 1.00 F capacitor. Determine the resulting charge on each capacitor. (6.67pC for C. 333uC for C2) How much energy is stored in each capacitor? (11.1pJ for C1, 5.55 J for C2) In Figure each capacitor has C 5.0 pF. Find the total capacitance of the circuit (2.5pF)Explanation / Answer
10) 5 and 5 ohm are in parallel
C = 5 + 5 = 10 pF
10 pF , 5 pF and 10 pF are in series
1/C = 1/10 + 1/5 + 1/10
C = 2.5 pF
