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. 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 3. 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 4. Power is defined as: work joules the rate at which work is done the conversion of energy 5. 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 6. 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 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. A short circuit has: low current no conductance too much resistance no resistance 9. In a series circuit, the voltage measured across a short will be: infinite voltage source voltage the normal voltage drop zero volts 10. 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 Loading … Question 1 of 10
