PDF STUDY GUIDE: Chapters (problems) 4(1-2), 5(1-4), 7(1-4). You will be given all fundamental constants and metric prefixes. Also: V=Ed. Q=CV (mass/charge of particles, definition of electron volt, parallal plate capacitance)

### Week 5

P

#### 2/13 (W)

python solution to bitbucket
```from math import pi
print(pi)
microAmps=50
Rmm=1

r=Rmm*1E-3 # milli is 10^-3
I=microAmps*1E-6 #microamp conversion
A=pi*r**2
#I=JA thetefore J=I/A

J=I/A #current density Amps/meterSquared = A/m^2
print('J = ',J,'A/m^2')
```

NewTest 2 problem 8.1
