Electrical Grid 2 Ch. 1

What is the first requirement for a basic electrical circuit to function properly?

• A) A conductor

• B) A load

• C) A source of electrical pressure or voltage

• D) A fuse

What is a closed circuit?

• A circuit with a broken path

• A circuit with a complete path for current to flow

• A circuit with no load

• A circuit with excessive current flow

Fill in the blank: A circuit that does not have a load, or in which the load has been bypassed, is known as a _________.

• short circuit

• open circuit

• closed circuit

• high resistance circuit

What is the purpose of a fuse in a circuit?

• To increase voltage

• To provide a complete path for current

• To burn open when current flow is excessive

• To transmit energy

In the context of short circuits, what happens when too much current flows through a conductor?

• The conductor will cool down

• The conductor will melt

• The conductor will expand

• The conductor will contract

What are the two basic types of circuits?

• A) Series and Parallel

• B) Direct and Alternating

• C) Open and Closed

• D) Positive and Negative

In a series circuit, how many paths are there for current flow?

• One

• Two

• Three

• Four

Which type of circuit allows multiple paths for current flow?

• Series circuit

• Parallel circuit

• Combination circuit

• None of the above

Lineworkers should never place themselves in series between two points of different potential, because:

• It can result in electric current passing through their body, causing electrocution.

• It might cause them to work slower.

• It could lead to operational delays.

• It increases overall system efficiency.

What voltage must be applied in order to achieve 5 amps of current flow? The two light bulbs are connected in series and have a resistance of 6 ohms each, totaling 12 ohms. Use the formula E = I x R to calculate the voltage.

• 2.4 volts

• 60 volts

• 2 volts

• 30 volts
