Chapter 3: Electric Circuits Questions
and Answers.
What is the complete path of an electric current, along with any necessary elements, such as a
power source and a load. - Answer Electric Circuit.
When the circuit is complete so that the current can flow, it is termed _____ or _____. - Answer
Closed, made.
When the path of current flow is interrupted, the circuit is termed ____ or ____. - Answer
Open, broken.
What does the opening and closing of electrical switches connected in series with electrical
loads control? - Answer The operation of loads in the circuit.
What must all electric circuits must have a ______ for electrons to flow through. - Answer
Complete path.
The series circuit also contains any safety devices, why? - Answer Needed to maintain safe
operation of the equipment components.
What is the change called when the voltage of a series circuit changes through each load? -
Answer Voltage drop.
What is voltage drop? - Answer The amount of voltage-electric pressure used or lost through
any load or conductor in the process of moving the current through that part of the circuit.
The _____ circuit has more than one path for the electron flow. - Answer Parallel.
What type of circuit allows the same voltage to be applied to all the electric loads connected in
it? - Answer Parallel circuit.
What type of systems are parallel circuits used in for all power wiring that supplies loads? -
Answer Heating, cooling, or refrigeration.
The _____ in a parallel circuit is determined for each part of the circuit. - Answer Current
draw.
