Question

F (Use a scientific notation) 6b) 1.9 E-3 C = _c (a convenient number in 1" blank, a prefix in 2nd ) 7) The charge on a capacitor is Q CV where C is its capacitance and V the potential difference between its 2 conductors (plates in the parallel plate capacitor case), what is Q if C·S60 μF and V a 6.0 volts. (1 coulomb 1 farad volt i.e. 1 C-1 F V) 8) (a) Draw a circuit diagram for charging a capacitor. You are given a capacitor, a 1.5 battery, a resistor for protection, and some wires. (b) Plot V vs. time, i.e. draw a charging curve. 9) (a) Draw a circuit diagram for discharging a capacitor. You have a fully charged capacitor, a resistor for protection, and some wires. (b) Plot V vs. time, i.e. draw a discharging curve. 10) Write out the formula for (a) percent error, and (b) percent difference. What is the major difference between the formulas?

Answer 1

"450 mu F = 450 times 10^-6 F = 45 times 10^-5 F ** 1 mu F = 10^-6 F 1.9 E - 3c E - 3 means 10^-3 than 1.9 E - 3c = 1.9 times 10^-3 c. C = 560 mu F = 560 times 10^-6F V = 6.0 volt Q = CV = 560 times 10^-6 times 6 Q = 336 times 10^-5 Q = 3.36 times 10^-3 C. \r\n charges on the capacitor at any time t is q = Q(1 - e^-t/RC) them val tag V = q/c = Q/C(1 - e^-t/RC) Q/C = voltage of the battery = 1.5 volt them V = 1.5(1 - e^-t/RC) \r\n charges on capacitor at any time t is q = Qe^-t/RC V = Q/C e^-t/RC % error =
