The circuit-triad of Figure 124.1 illustrates the three basic conceptual components of an electric/electronic circuit.
(a) Describe the three basic conceptual components of the circuit-triad.
(b) What roles do amplification and switching play in the circuit-triad?
(c) What roles do active and passive elements play in the circuit-triad?
(d) The electrical/electronic circuits of a given automobile consists of an automotive battery connected to the parallel connections of the following components: headlights, taillights, starter motor, fan, power locks, and dashboard panel.
d(i) Illustrate the circuits. How many meshes in the illustration?
d(ii) How many loops in the illustration?
Pj Problem of Interest is of type force (push). Circuits are essentially power distributors. They realize this function by pushing electrons around the circuits.
(a)Power source: voltage or current source that provide circuit energy. It can be independent (not dependent on changes in condition of circuit) or dependent (dependent on changes in condition of circuit).
Signal continuity: current produced must follow a closed path.
Load: user of the power supplied by the power source.
(b) Amplification amplifies signal. Switching turns signal on and off.
(c) Active elements are power sources (voltage or current sources). They supply energy to the circuit.
Passive elements (resistors, capacitors, inductors) are receptors of circuit energy. They either convert it to another form or store it in an electric or magnetic field.
(di) A mesh is a loop that does not contain other loops. So, there are six meshes (figure 124.1d)
(dii) A loop is any closed connection of branches. A loop can contain other loops. So, try it.
The point . is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.

The Universe is composed of matter and radiant energy. Matter is any kind of mass-energy that moves with velocities less than the velocity of light. Radiant energy is any kind of mass-energy that moves with the velocity of light.
