CAPACITANCE

THE LEARNING GOALS
FOR THIS CHAPTER ARE:
Know how to use circuit models for inductors
and capacitors to calculate voltage, current,
and power
Be able to calculate s

Here again summing up of first two result in third equation, which
is indicative of independent/dependent nature of these equations.
We now introduce double subscript notation e.g. Vab to represent
potential difference between points a and b such that p

Example 2.16; In the network drawn here, find VS and power loss in
the transmission line represented by 20 resistor?
Sine we know the load voltage and
load resistance, we can apply Ohms
Law to find line current
IL = VLOAD/RLOAD = 458.3k/220 = 2.083 kA,

Inductor Time Constant
Maximum current that can flow in RL DC circuit depends on circuit
resistance alone and is revealed by Ohms Law i.e. I = V/R.
However the rate at which current rises (also decays) depends upon
the amount of inductance and resistanc

In DC circuits the rate at which voltage rises and current decays in
charging capacitor (or vice versa when a capacitor is discharging)
depends on amount of resistance and capacitance in the circuit.
This property of capacitors help generate different e

Conduct of Course
BEE (EEN-1144) is a 3 + 1 credit course i.e. theory contact hours
and Lab contact hours are 3 hours each.
Relevant information has already been placed on UCP website,
everyone must read it in own interest and clarify doubts if any,
wit

Class Work: In the circuit drawn below, compute the amount of
voltage developed across the capacitor and the resistor after one
minute and ten seconds of switching on the circuit?
T = 7 M x 5 F = 35 s.
1 min and ten s = 2 x T = 70 s.
In 2 x T i.e. 70 s,

Example 3.4; Find the node voltages in
the network drawn here that has voltage
controlled dependent current source?
At node-1 V1/R3 + (V1 V2)/R1 IA = 0
OR; (1/R1 + 1/R3)V1 (1/R1)V2 = IA
Putting the values, (0.001 + 0.0005)V1 (0.001)V2 = 0.002 A
OR; 1

Most common way of specifying AC is by stating its rms value
For example; all measuring instruments display rms value of AC.
Same amount of ACrms and DC produce equal quantity of heat in a
given resistive circuit
This happens because equal amounts of

Example 2.3; Find the value of voltage across and power absorbed
by resistor in a circuit of fig 2.4c above?
Answer; Vs = I/G = 0.5 mA/50 S = 10 V. Alternatively, since
R = 1/G = 20 k, therefore, Vs = IR = 0.5 mA x 20 k = 10 V.
Power can be found as P

Circuits with Dependent Sources
On encountering a dependent source or sources in a single loop or a
node-pair circuit, strategy would be to treat them as independent
sources and write KVL or KCL equations in usual manner
Next write equations that specif

In real life a circuit is not always composed of resistors only.
A practical circuit more often contains capacitors and inductors in
different series and parallel combination co-existing with resistors
What is an inductor and a capacitor?
We will stud

Loop Analysis
Loop analysis uses KVL to determine set of loop currents, and as we
processed known node voltages in node analysis, Ohms Law can then
be applied to known loop currents to reveal network voltages
In general there are exactly B N + 1 linearl

with 3 k resistor and supplied by 65 V source at 80 kHz?

the shown circuit after 11.5 s of
closure of its switch?
T = L/R = 0.02/5200 = 3.846 s.
11.5 3 x T.
In 3 x T current would rise to 95% of its final value.
Since final value of current IMAX= V/R = 100/5200 = 19.231
