Exam 11: Network Theorems

Delta (or Wye) ______________ are generally used in three-phase ac power circuits.

Network theorems usually provide shorter methods than Kirchhoff's laws for solving a circuit.

Components such as transistors, semiconductor diodes, and electron tubes are

When all the R values are equal in a network, it is ______________.

A combination of components, such as resistances, interconnected to achieve a particular end result is a

______________ theorem provides a shortcut for finding the common voltage across any number of parallel branches with different voltage sources.

While using superposition, disabling a source so that it cannot generate voltage or current without changing the resistance of the circuit is called

What theorem or law states that in a network with two or more sources, the current or voltage for any component is the algebraic sum of the effects produced by each source acting separately?

The expression, temporarily killing a source means disabling the source so that it cannot generate voltage or current without changing the resistance of the circuit.

Of all the different theorems, the superposition theorem is by far the most widely used.

When using superposition, linear means that the current is proportional to the applied voltage.

Theorems cannot be applied to ac networks.

Networks with resistors, capacitors, and air-core inductors are generally linear and bilateral.

Components that do not amplify or rectify are called

When the current is the same amount for opposite polarities of the source voltage, it is

The accepted assumption is that an ideal voltage source has an internal resistance of

______________ theorem is used to simplify a network in terms of currents instead of voltages.

A current source symbol with a dashed or broken arrow indicates the direction of ______________ current flow.

Thevenin's theorem cannot be used to find the current through a resistor that is in the center of a bridge circuit.

When using superposition, bilateral means that the current is the same amount for opposite polarities of the source voltage.
