Power (measured in Watts, W) is the rate at which electrical energy is converted into heat or some other form of energy. Since we all know that energy is conserved, a circuit needs a power supply or battery, which converts another form of energy into electrical energy, in order for it to operate.
The goal of this text is to introduce the theory and practical application of analysis of DC electrical circuits.

Identify the term power, and state three formulas for computing power. Compute circuit and component power in series, parallel, and combination circuits. Compute the efficiency of an electrical device. Solve for unknown quantities of resistance, current, and voltage in a series circuit.
Power is the time rate of expending or absorbing energy, measured in watts (W); mathematically: where p is power in watts (W), w is energy in joules (J), and t is time in seconds. This power is time-varying, called the instantaneous power.
Resonant converters and RF (radio frequency) power circuits (PDF - 1.6 MB) This section provides the lecture notes from the course along with a list of lecture topics.
