Question 5

Cells and other voltage sources are often connected in series to obtain ____ voltages.

A)lower
B)similar
C)higher
D)grounded

Question 6

The total power dissipation is less than the sum of all the individual power ratings.

Question 7

In electrical theory, ____ are often called ground, regardless of whether or not they are actually connected to the earth.

A)pole points
B)references
C)circuit grounders
D)reference points

Question 8

In some applications, voltage division is achieved by means of potentiometers.

Question 9

Voltage ____ are series circuits in which the source voltage is divided among the resistors proportionally to their ohmic values.

A)subtractors
B)multipliers
C)additions
D)dividers

Question 10

When series circuits are used for the purpose of obtaining different voltages from one voltage source, they are known as voltage subtractors.

Question 11

To determine the polarity of a voltage drop, we simply consider the ____ of the current.

A)location
B)direction
C)magnitude
D)strength

Question 12

In discussing the voltage distribution of a circuit, it is not good enough to merely refer to the magnitude of the voltages, because equal consideration should be given to the polarity of the voltages.

Question 13

The characteristics of series circuits can be summed up in three rules, which are that voltage drops add, current remains the same, and resistance ____.

A)adds
B)remains the same
C)subtracts
D)increases

Question 14

The total voltage of a series circuit is equal to the sum of all the voltage drops.

Question 15

In the series-aiding method of connecting voltage sources, the positive pole of one source always connects with the positive pole of another source.

Question 16

When any number of devices are connected so that there is only a single circuit path for electrons, the devices are in series.

Question 17

If there are seven lamps in the series circuit, but one lamp has been removed, we can use the formula ____ to determine how much voltage, if any, exists across the open socket.

A)E = R - I
B)E = R + I
C)E = IR
D)E = I/R

Question 18

Since the current flow through a series circuit is the same at all points in the circuit, the voltage drop across any particular resistance is equal to the total circuit current plus the value of that resistor.

A)charges
B)resistors
C)voltages
D)watts
