Exam 11: Network Theorems

Norton's theorem is used

What theorem or law provides a shortcut for finding the common voltage across any number of parallel branches with different voltage sources?

______________ a current source kills its ability to supply current without affecting any parallel branches.

Network theorems can be applied to

With appropriate values known, voltage can be calculated as

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

Delta and wye networks are often used in circuits involving

The Thevenin voltage (V_TH) is equal to

In order to superimpose currents and voltages, all components must be

The superposition theorem 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.

Another term for opening a current source is to

An ideal current source is assumed to have an internal resistance of ______________ ohms.

The Thevenin equivalent circuit driving terminals A and B changes whenever R_L changes.

What theorem or law states that an entire network can be replaced by a single current source in parallel with a single resistance?

Of all the network theorems, ______________ theorem is by far the most widely used.

Passive networks have

What is a specific example of the general principle that any voltage source with its series resistance can be converted to an equivalent current source with the same resistance in parallel?

By Thevenin's theorem, many sources and components can be represented by an equivalent series circuit with respect to any pair of terminals in the network.

______________ theorem says that any network can be represented by a voltage source and a series resistance.

All components must be nonlinear and unilateral to superimpose currents and voltages.
