Series Circuits Online Test – Multiple Choice Questions and Answers Posted on May 26, 2024May 26, 2024 by engineer2 Comments 1. An 8-ohm resistor is in series with a lamp. The circuit current is 1 A. With 20 V applied, what voltage is being allowed for the lamp? 4 V 8 V 12 V 20 V 2. How will an open resistor affect a series circuit? Total resistance will decrease The open resistor will drop 0 V No current will flow in the circuit Current will flow around the open resistor 3. When a battery is connected to a series circuit, it delivers current based only upon: total resistance average resistance primary/secondary difference the polarity connections 4. An 8-ohm resistor is in series with a lamp. The circuit current is 1 A. With 20 V applied, what voltage is being allowed for the lamp? 4 V 8 V 12 V 20 V 5. If series current doubles, then: voltage is doubled resistance is halved voltage is reduced resistance is doubled 6. The voltage drop across a series resistor is proportional to what other value? wattage rating the amount of time the circuit is on total resistance its own resistance 7. A string of resistors in a series circuit will: divide the source voltage in proportion to their values reduce the power to zero cause the current to divide increase the source voltage in proportion to the values 8. Power is defined as: the rate at which work is done work joules the conversion of energy 9. In a series circuit, the voltage measured across a short will be: source voltage infinite voltage zero volts the normal voltage drop 10. With a total resistance of 3300 ohms and a 45 V source, if R3 is 1200 ohms, what will be its voltage drop? 10.90 V 32.72 V 16.36 V 15.00 V Loading … Question 1 of 10
