Review:OpenandShortinSeriesCircuits
Open Circuits
Current is zero
Entire source voltage is applied to the open
Short Circuits
All current flows through the short
The short-circuited component has zero c

Review:ParallelCircuitsAnalysis
The voltage is the same across any component
in the parallel circuit
Vs = V1 = V2 = . = VN
Apply Ohm's law to find the current through
each resistance.
I1 = V1 R1
I2 = V2

Review:SeriesParallelCircuitAnalysis
Identify the series-parallel relationship
Plan a strategy to solve the circuit
If the most upper level connection is in series,
Start with find RT and IT
Use curren

Review:LoadingEffect
RL connected to the voltage divider will
Increase total current
Lower the total resistance
Lower the output voltage
Loading effect is ignorable is RL is much greater
than R2.

Homework 1
2. What is the charge in coulombs of the nucleus of a chlorine atom?
One Coulomb is the total charge by 6.25x1018 electrons.
Atom number is 17, so charge of chlorine atom is:
Q=
17 elctrons
6.25 x 10 electrons /coulombs
18
Q= 2.

Homework 2
24. A small solar cell is connected to a 27K resistor. In bright sunlight, the
solar cell looks like a current source that can supply 180 A to the
resistor. What is the voltage across the resistor?
V=IxR
V=(180x10-6 A)
