Electronics-Series Circuits Question and Answer

Electronics-Series Circuits Question and Answer
11. In a series circuit, the voltage measured across a short will be:
  • source voltage
  • infinite voltage
  • zero volts
  • the normal voltage drop
Show Answer
12. A series circuit current:
  • remains the same through each component
  • is the same as the individual resistances
  • is subtracted by each component
  • varies through each component
Show Answer
13. If 5 V and 16 V power supplies are connected in series-opposing, what is the total voltage?
  • 11 V
  • 16 V
  • 21 V
  • 80 V
Show Answer
14. How will an open resistor affect a series circuit?
  • Current will flow around the open resistor.
  • The open resistor will drop 0 V.
  • Total resistance will decrease.
  • No current will flow in the circuit.
Show Answer
15. The voltage drop across a series resistor is proportional to what other value?
  • total resistance
  • its own resistance
  • wattage rating
  • the amount of time the circuit is on
Show Answer
16. Resistance in a series circuit will:
  • control the voltage
  • double the current
  • halve the power
  • oppose current
Show Answer
17. When a battery is connected to a series circuit, it delivers current based only upon:
  • primary/secondary difference
  • total resistance
  • the polarity connections
  • average resistance
Show Answer
18. What determines the total resistance in a series circuit?
  • the largest resistor
  • the sum of the resistors
  • the largest resistor minus the smaller
  • the smallest resistor
Show Answer
19. If two resistors have the same voltage drop in a series circuit, it means:
  • they are connected in parallel
  • they are of unequal value
  • the voltage has doubled
  • they are of equal value
Show Answer
20. If series resistors dissipate 16 mW, 107 mW, 146 mW, and 243 mW, what is the total power consumed by the circuit?
  • 128 mW
  • 269 mW
  • 512 mW
  • 1024 mW
