Question 1

-If R₃ opens in Figure 6-1, VR₁ ________.

Accepted Answer

A

Question 2

If two resistors are in parallel, they carry the same current.

Accepted Answer

False

Question 3

-R₁ is in series with the series combination R₂ and R₃ in Figure 6-1.

Accepted Answer

False

Question 4

Thevinizing a circuit creates an equivalent series circuit.

Accepted Answer

Thevenin's theorem states that any two-terminal network can be replaced by an equivalent circuit consisting of a voltage source in series with a resistor. This equivalent circuit is called the Thevenin equivalent circuit, which is a series circuit.

Question 5

Maximum power is achieved when the load resistance is approximately two times the source
resistance.

Accepted Answer

Maximum power transfer occurs when the load resistance is equal to the source resistance, not two times the source resistance.

Question 6

Two or more resistors connected in series form a circuit known as a voltage divider.

Accepted Answer

This statement is true. In a series circuit, the total voltage is divided among the resistors in proportion to their resistance values. Therefore, a series circuit with two or more resistors is known as a voltage divider.

Question 7

-If  in Figure 6-1, the total resistance equals ________.

Accepted Answer

The answer of 
-If  in Figure 6-1, the total...

Question 8

If two resistors are in parallel, they drop the same voltage.

Accepted Answer

In a parallel circuit, all components share the same voltage across them because they are connected to the same two nodes.

Question 9

A bridge circuitʹs resistances must all be of the same value to be in a balanced condition.

Accepted Answer

The answer of A bridge circuitʹs resistances must all be...

Question 10

A loaded voltage divider is a series-parallel circuit.

Accepted Answer

A loaded voltage divider consists of resistors in series and parallel configurations, making it a series-parallel circuit.

Question 11

-In Figure 6-1, R₂ is connected in ________.

Accepted Answer

R₂ is connected in parallel with R₃ because they share the same two nodes, meaning they have the same voltage across them.

Question 12

-R₁ is in series with R₃ in Figure 6-1.

Accepted Answer

Without the context of Figure 6-1, it is impossible to determine the configuration of R₁ and R₃.

Question 13

A series-parallel circuit consists of resistors in both series and parallel.

Accepted Answer

A series-parallel circuit is a combination of resistors in series and parallel in the same circuit.

Question 14

A voltmeter, when connected across a component, can be viewed as being a resistor in series with
that component.

Accepted Answer

A voltmeter is connected in parallel with a component, not in series. It has a high internal resistance to minimize the current drawn from the circuit.

Question 15

-In Figure 6-1, R1 is connected in ________.

Accepted Answer

Without the actual Figure 6-1, it's impossible to determine the specific configuration of R1 with respect to R2 or R3.

Question 16

The voltage across any open in a series-parallel circuit will be the source voltage.

Accepted Answer

In a series-parallel circuit, if there is an open circuit, the voltage across the open will equal the source voltage because there is no current flow, and thus no voltage drop across other components.

Question 17

-If  in Figure 6-1, PR2 equals ________.

Accepted Answer

The answer of 
-If  in Figure 6-1, PR2 equals...

Question 18

No problems could occur if a 10 V source and a 20 V source were connected in parallel.

Accepted Answer

Connecting two voltage sources with different voltages in parallel can cause a short circuit or damage the sources due to the voltage difference, leading to excessive current flow.

Question 19

-R₂ is in parallel with R₃ in Figure 6-1.

Accepted Answer

R₂ and R₃ are connected between the same two nodes, so they are in parallel.

Question 20

-R₁ is in series with the parallel combination R₂ and R₃ in Figure 6-1.

Accepted Answer

In a series-parallel circuit, R₁ is in series with the parallel combination of R₂ and R₃, meaning the current flows through R₁ before splitting between R₂ and R₃.
