Technical folks often use block diagrams to describe the functionality of complex electronic systems, like the radio receiver shown in Figure 2-7.
An analogy that may help you understand voltage measurement is distance measurement. ” On the other hand, you may say, “I’m five miles from home,” and you’ve stated your distance from a reference point (home). 5 volts with respect to ground,” that makes perfect sense. 5 volts are dropped across the light bulb. ) The important thing to notice here is that as you travel around a DC circuit, you “gain” voltage going from the negative terminal of the battery to the positive terminal (that’s known as a voltage rise), and you “lose” or drop voltage as you continue in the same direction across circuit components.
Behind each wall socket is a wire that runs through your house or office and eventually connects to a metal post that makes good contact with the ground. This arrangement provides extra protection for circuits that use large amounts of current; shipping dangerous current directly into the earth gives it a safe place to go after it’s done its work — or gives it something to do besides destroy things. Such was the case when Ben Franklin’s lightning rod provided a direct path for dangerous lightning to hit the ground — instead of a house or person.
