Description

= 4 + 9.33 = 13.333 C.

Practice Problem 1.1 Calculate the amount of charge represented by six million protons.

Solution:

Practice Problem 1.4 −19

Each proton has +1.602 × 10 million protons will have

C. Therefore 6

C.

To move charge q from point a to point b requires −30 J. Find the voltage drop ν ab if: (a) q=6 C (b) q=−3 C.

Practice Problem 1.2

Solution:

C / protons × 6 000 000 protons =

The total charge entering a terminal is given by −2 t q=( 10−10 e ) mC, find the current at

(a)

ν=

∆ w −30 =−5 V, = 6 ∆q

(b)

ν=

∆ w −30 =10 V. = ∆ q −3

t=1.0 s.

Solution: f (t)=10−10 e−2t

Practice Problem 1.5

f ' ( t ) =−2 ×(−10 e−2t )

Find the power delivered to the element at t=5 ms if the current remains same ( i=5 cos 60 πt A) but the voltage is:

f ' ( t ) =20 e−2 t Therefore, current at

t=1.0 s.

' −2 f ( 1 )=20 e
