EEE 202 CIRCUITS 1 QUESTIONS AND ANSWERS
CURRENT - CORRECT ANSWER✅✅Time rate of change of electric charge, I (amps)
VOLTAGE - CORRECT ANSWER✅✅Electromotive force or potential or potential, difference in energy
level of unit charge located at two different points, V (volt)
POWER - CORRECT ANSWER✅✅P = IV (in watts)
DIRECT CURRENT - CORRECT ANSWER✅✅(DC) Batteries and some special generators
ALTERNATING CURRENT - CORRECT ANSWER✅✅(AC) Household current which varies with time
PASSIVE SIGN CONVENTION - CORRECT ANSWER✅✅Current should enter positive voltage terminal
When the POWER is positive, ... - CORRECT ANSWER✅✅Element absorbs power
When the POWER is negative, ... - CORRECT ANSWER✅✅Element supplies power
ACTIVE ELEMENTS - CORRECT ANSWER✅✅Can generate energy. (i.e. voltage and current sources,
batteries)
PASSIVE ELEMENTS - CORRECT ANSWER✅✅Can't generate energy. (i.e. resistors, capacitors and
inductors [but can store energy])
INDEPENDENT SOURCES - CORRECT ANSWER✅✅(Voltage or current, DC or AC) Does not depend on
other voltages or currents in the circuit
RESISTORS - CORRECT ANSWER✅✅Dissipates electrical energy (usually as heat), (ohms)
