Figure (a)’s circuit is valid

A resistor stores electrical energy.

Find the Thevenin Equivalent resistance for the circuit :

In Norton simplification: Thevenin to Norton. The short circuit current (Norton equivalent current) is 2.5 A

Find the voltage V in the following circuit:

Thevenin Simplification: Series Resistors. The equivalent Thevenin Voltage for the circuit above is 7V.

Consider the following circuit. What resistance RL maximizes power transfer from the 12 V source?

Suppose the voltage measured across a 1.5 F capacitor is 2 V. What is the charge in coulombs stored on the capacitor?

When the voltage across a current source changes sign, the current changes direction.
