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
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
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
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.
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
16. Resistance in a series circuit will:
- control the voltage
- double the current
- halve the power
- oppose current
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
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
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
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
