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 2. With 20 V applied, an 8-ohm resistor is in series with a lamp. When the lamp is removed, what voltage will be read across the lamp socket? 0 V 8 V 12 V 20 V 3. A string of resistors in a series circuit will: cause the current to divide reduce the power to zero divide the source voltage in proportion to their values increase the source voltage in proportion to the values 4. In a series circuit, the voltage measured across a short will be: infinite voltage source voltage the normal voltage drop zero volts 5. A series circuit current: remains the same through each component is the same as the individual resistances varies through each component is subtracted by each component 6. A short circuit has: low current no conductance too much resistance no resistance 7. 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 8. Power is defined as: work joules the rate at which work is done the conversion of energy 9. Kirchhoff’s voltage law states that: the algebraic sum of the resistances is equal to the sum of the voltages the algebraic sum of the individual currents around a closed loop is zero the sum of the voltage drops in a series circuit is equal to the total applied voltage the voltages developed across each element in a series circuit are identical 10. 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 Loading … Question 1 of 10
