Series-Parallel Circuits Online Test – Multiple Choice Questions and Answers 1. In a series–parallel circuit, individual component power dissipations are calculated using: individual component parameters a percent of the total power depending on resistor ratios total current squared multiplied by the resistor values a percent of the voltage division ratio squared 2. A device able to supply electrical energy is a ________ nonconductor battery conductor microwave 3. In a series–parallel circuit consisting of R1 and R2 in series and connected in parallel with R3, if R1 opens, then R2‘s voltage will: increase remain the same decrease cannot tell 4. The positve (+) and negative (-) ends of the battery are called ______ circuit diagram battery knobs battery terminals battery sides 5. When a Wheatstone bridge is in a balanced condition, the center voltmeter in the bridge will read: twice the source voltage half the source voltage zero volts the same as the source voltage 6. The first goal to accomplish in analyzing a complex series-parallel circuit is to solve for all the voltage drops solve for the total current and resistance equate all series components equate all parallel components 7. If R1 is in series with parallel connected to R2 and R3, what happens to total current if R2 opens? cannot tell remains the same increases decreases 8. With 21 V applied, if R1 = 5 ohms, R2 = 35 ohms, and R3 = 14 ohms, what is the current of R2 if R1 is series connected with parallel circuit R2 and R3? 200 mA 400 mA 600 mA 800 mA 9. A Wheatstone bridge can be used to determine an unknown current voltage resistance power 10.
