Question

1. When charging an RC circuit, the value of the voltage after one time constant % of its final value. s 2. When discharging a RC circuit, the value of the voltage after one time constant is teow % of its initial value. Knowing that the charge, Q, voltage, V, and capacitance, C, are related by the equation, Q 3. CV, what is the equation of capacitance? 4. Name few places where you use a capacitior. Leustenes xi0 6.

The buildup of charge on a capacitor with time is given by Q-Ce). The discharge of charge on a capacitor with time is given by Q-CCeAD when C-5 ?F , R = 2.5 KS2, t=1 s, and C-10V,Q= For the previous question, if t = 4 s, Q C. 10, C.

Explanation / Answer

1. 36.8 % of final value.

2. 63.2 % of intiial value.

3. C= Q/V

4. Fan , oscillator, camera flash.

8. Q= 5*10*(1- e^(-(2.5*5*10^-3)))

= 50 uC
