1. ### A 10.0 V battery is connected to a 5.6 pF parallel-plate capacitor. What is the charge on each plate?

C=Q/V C= capacitance Q= charge V= voltage 10v*5.6pF = 56 picocoulombs +q on one -q on the other

2. ### A 3400 pF air-gap capacitor is connected to a 23 V battery.?

this page worked for me. not my work so i can't take credit. http://www.cramster.com/physics-answers-5-644331-cpi0.aspx this would have been simple if it just asked for the amount of charge

3. ### A parallel-plate air capacitor has a capacitance of 920 pF. The charge on each plate is 2.55 uC?

1st answer is correct with respect to the potential differences before and after doubling the separation. However, work is equal to the change in potential energy stored in the capacitor. PE = V^2C/2. The separation doubles...

6. ### a 13,000 -pF capacitor holds 17X10 ^-8 C of charge What is the voltage across the capacitor?

q = (capacitance)*(Voltage) Voltage = q/c = (.000,000,17C)/(.000,000.013F) = 13.07692 Volts

7. ### A 100-pF parallel-plate capacitor is made of two metal plates. The area of each plate is 100 mm2. What is the?

1.)C= (ε0)*A/d 100*10^-12=(8.8*10^-12)*(100*10^-6)/d (1mm=10^-3m) d=8.8*10^-5 (B) 2.) B the geometry of the conductors 3.) B. The charges on the two plates will remain unchanged, but the voltage will become zero.

10. ### A drop pf olive oil when released into mixture of water and alcohol acquires a spherical shape.?

While in air, the weight of the drop of oil dominates the force of surface tension. But inside the mixture the weight is neutralised by the upthrust. Thus the only force remaining unbalanced is the force of surface tension. So under the action of this force the...
