Deck 5: Series-Parallel Circuits

Question 1

-The equivalent resistance of the circuit in the accompanying figure is 30 $\Omega$ .

Answer 1

False

Question 2

After the total resistance of a circuit is found, the total current, as well as the current in other parts of the circuit, can be determined according to ____________________ law.

Answer 2

Ohm's

Question 3

-For the circuit in the accompanying figure, determine the total resistance for the equivalent series circuit.

Answer 3

In Figure 5-6, the equivalent resistance of the parallel resistors R2 and R3 is 12 ohms. In an equivalent series circuit, since R1 and R2,3 are in series: RT=R1 + R2,3 = 20 $\Omega$

Question 4

The methods used to determine current, voltage, and resistance for series and parallel circuits apply to combination circuits as well.

Question 5

Determine the total current for the three resistors shown in the accompanying figure.

Question 6

Solving problems in series-parallel circuits is made easier by resolving these circuits into ____________________ circuits.

Question 7

The circuit shown in the accompanying figure is an example of a(n) ____________________ circuit.

Question 8

-The equivalent resistance of this circuit in the accompanying figure is less than 9 $\Omega$ .

Question 9

Combining series and parallel circuits is rarely necessary.

Question 10

In many instances, it is desirable to group voltage sources, particularly batteries, to obtain the correct ____________________ and current capacity.
