understanding resistance in DC combination circuits

Question 1

Any circuit in which the current is split or follows two (or more) alternative paths is called a ? circuit.

Answer 1

parallel

Question 2

Any circuit in which the same current flows through all components is a ? circuit.

Answer 2

series

Question 3

To solve unknown values in a combination circuit, use series circuit rules for those sections of the circuit that are connected in series, and parallel circuit rules for those sections connected in parallel.

Answer 3

true

Question 4

In a series circuit, the ? is the same at any point in the circuit.

Answer 4

current

Question 5

In a series circuit, the total resistance is ?

Answer 5

the sum of the individual resistances

Question 6

In a ? circuit, the sum of the voltage drops of the individual resistors must equal the applied voltage.

Answer 6

series

Question 7

In a ? circuit, the total current is the sum of the current through all of the circuit paths.

Answer 7

parallel

Question 8

In a parallel circuit, the total resistance is ?

Answer 8

equal to the reciprocal of the sum of the reciprocals of the branch resistances

Question 9

When it is difficult to recognize which parts of a combination circuit are series connected and which are parallel connected, it is often necessary to ?

Answer 9

redraw the circuit

Question 10

In reducing series-parallel circuits to their simplest form, the equivalent circuit is usually represented by a single resistor that is connected in parallel with the voltage source.

Answer 10

false

Question 11

One of the basic steps in reducing a combination circuit to its simplest form is to ?

Answer 11

substitute the equivalent values from each simple parallel or series circuit into the original circuit
