Exam 2 - Intro to EE Question and
answers rated A+ 2025/2026
to find V thevenin - correct answer ✔convert a to b to OPEN-CIRCUIT
to find i s.c - correct answer ✔convert a to b to SHORT-CIRCUIT
short-circuit: v = 0
when finding R thevenin - correct answer ✔independent sources become open and short circuits to
then combine series and parallel resistors
you can add independent voltage sources like you do for R in series - correct answer ✔Vs+Vs = Vs,eq
Capacitance eq - correct answer ✔C = (εA)/d
ε is permittivity of dielectric material
A is surface area
d is distance bw conducting sheets
Capacitor (i-v) characteristic - correct answer ✔under steady state, no variation with time THUS i=0 ,
capacitors are replaced by an OPEN CIRCUIT
Pc(t) [capacitor power] - correct answer ✔The polarity of Pc (t) can be positive or negative.
For Pc (t) positive, capacitor consume power.
For Pc (t) negative, capacitor deliver power
