Answer the following statement(s) true (T) or false (F)
1. Today, one would be hard-pressed to find some electronic device that doesn’t have semiconductor components. 2. Solid-state devices such as the PN junction diode and the transistor have replaced vacuum tubes in very high- power radio and TV transmitters. 3. The PN junction diode is composed of P-type material such as boron and N-type material such as arsenic that are chemically combined. The boron atoms have an overall positive charge. The arsenic atoms of N-type material have an overall negative charge. 4. If a diode reads infinite in both the forward and reverse bias conditions, it is bad (open) and must be replaced. 5. You can replace a bad diode with any diode in your parts bin.
