EEE 202 - CIRCUITS 1 EXAM QUESTIONS ANSWERED CORRECTLY LATEST UPDATE 2026
CURRENT - Answers Time rate of change of electric charge, I (amps)
VOLTAGE - Answers Electromotive force or potential or potential, difference in energy level of unit
charge located at two different points, V (volt)
POWER - Answers P = IV (in watts)
DIRECT CURRENT - Answers (DC) Batteries and some special generators
ALTERNATING CURRENT - Answers (AC) Household current which varies with time
PASSIVE SIGN CONVENTION - Answers Current should enter positive voltage terminal
When the POWER is positive, ... - Answers Element absorbs power
When the POWER is negative, ... - Answers Element supplies power
ACTIVE ELEMENTS - Answers Can generate energy. (i.e. voltage and current sources, batteries)
PASSIVE ELEMENTS - Answers Can't generate energy. (i.e. resistors, capacitors and inductors [but can
store energy])
INDEPENDENT SOURCES - Answers (Voltage or current, DC or AC) Does not depend on other voltages
or currents in the circuit
RESISTORS - Answers Dissipates electrical energy (usually as heat), (ohms)
Ohm's Law - Answers V = IR,
V(t) = i(t)R
KVL - Answers Kirchhoff's Voltage Law: Sum of voltages around a loop in circuit = 0
KCL - Answers Kirchhoff's Current Law: Sum of all currents entering/leaving a node = 0.
Dependent Source - Answers Magnitude of a function of another voltage or current in the circuit
Resistors in series - Answers R1 + R2 +R3 = R4
Resistors in parallel - Answers 1/R1 + 1/R2 + 1/R3 = 1/Req
Current in Parallel - Answers I1 + I2 + I3 = Itotal
Voltage Division equation (in series) - Answers V1(t) = V(t) (R1 / (R1 + R2))
Current Division equation - Answers I1 = I (R2 / (R1 + R2))
