Dc Theory 4 Lesson 2

Question: Ohm’s Law can only be applied to series and parallel circuits; to solve for combination circuits, Kirchhoff’s Law must be applied.

True or False?

Answer: False

Question: For combination circuits, trace the current paths through the circuit to determine which resistors are connected in series and which are connected in parallel.

True or False?

Answer: True

Question: The first step when solving combination circuits is to reduce the combination circuit to a simpler circuit one part at a time.

True or False?

Answer: True

Question: Three resistors in parallel can be reduced to a single equivalent resistor.

True or False?

Answer: True

Question: In a combination circuit, the amount of current that passes through each resistor is exactly the same.

True or False?

Answer: False

Question: No matter how complex, a combination circuit can be reduced to a single voltage, current, and resistance.

True or False?

Answer: True

Question: In a combination circuit, the current leaving the source is ? the current returning to the source.

Answer: The Same As

Question: In parallel circuits, a person can easily calculate the current for a branch when the voltage applied and the resistance are known for that branch.

True or False?

Answer: True

Question: In parallel circuits, when the total current through the circuit and the resistance of each component is known, a person can calculate the voltage drop for each component in that circuit by multiplying the total current times the resistance of the component.

True or False?

Answer: False

Question: Branch-circuit currents are generally calculated by applying ? to the voltage across the branch and the branch resistance.

Answer: Ohm’s Law
