Chapter 5 Review Questions and Circuit Analysis 1. The two basic circuit types are __________.  series-parallel series and parallel series and reactive series and combination 2. Series circuits _________.  have only one series component have only one current path have the same voltage across each path dissipate equal power across each component 3. The current passing through each component in a series circuit __________.  is proportional to the resistance of each component is proportional to the power dissipated by each component is the same throughout each component 4. Voltages are __________ with respect to ground.  positive negative either positive or negative neither positive nor negative 5. KVL states that __________.  the sum of all power dissipations in a series circuit equals the applied power the current is the same at any point in a series circuit the voltage drop is constant in any series circuit the sum of all voltage drops in a series circuit equals the applied voltage   When multiple components are connected to a common ground point, this is often referred to as __________.  ground-loop path common signal path system-return path ground-loop short

Chapter 5 Review Questions and Circuit Analysis When measuring the voltage across a load, the black lead across the voltmeter is connected to __________.  ground the positive terminal of the source the side of the load leading back to the negative terminal of the source the side of the load leading back to the positive terminal of the source 9. When there is an open in a series circuit __________.  the current drops to zero the supply voltage is dropped across the open power dissipation drops to zero all of the above You are measuring the voltage across a shorted resistor in a single resistor circuit using a DMM. You do not measure the full applied voltage across the component, though it is close. The reason this happens is __________.  the meter is faulty you forgot to calibrate the meter connecting the meter completes the circuit DMMs have low internal resistance 13. The difference between earth ground and chassis ground is __________.  the number of ground connections one is a negative ground and the other is a positive ground earth ground may not be at 0 V chassis ground may not be at 0 V 10. A blown fuse in a series circuit is usually a sign that _______  there is a short there is an open either a) or b) neither a) nor b)
