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 2. In a series circuit, the voltage measured across a short will be: source voltage infinite voltage zero volts the normal voltage drop 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. 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 5. 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 6. 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 7. Kirchhoff’s voltage law states that: the voltages developed across each element in a series circuit are identical the sum of the voltage drops in a series circuit is equal to the total applied voltage the algebraic sum of the individual currents around a closed loop is zero the algebraic sum of the resistances is equal to the sum of the voltages 8. 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 9. If series current doubles, then: voltage is doubled resistance is halved voltage is reduced resistance is doubled 10. 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 Loading … Question 1 of 10
