Find the total current flowing. Use B. Find the voltage drop across the lamp. Use VL = IT × RL VL = C. Have the voltage and current increased or decreased? Answers A. B. 3 Ω = 14 V C. Both have reduced in value. 29. In many applications, a lowering of voltage across the lamp (or some other component) may be unacceptable. 27. 27 If you choose a 20 V zener (that is, one that has a 20 V drop across it), then the lamp will always have 20 V across it, no matter what the output voltage is from the generator (provided, of course, that the output from the generator is always above 20 V).

VA = 10 V; VB = 0 V B. No current is flowing because the switch is open. C. 10 V. If the switch is open, point A is the same voltage as the positive battery terminal and point B is the same voltage as the negative battery terminal. 33. 14 includes a single pole double throw switch. The position of the switch determines whether lamp A or lamp B is lit. 14 Questions A. In the position shown, which lamp is lit? B. Can both lamps be lit simultaneously? Answers A. Lamp A. B. No, one or the other must be off.

2 Answer The anode is P material, the cathode is N material. 3. Diodes are useful because electric current will flow through a PN junction in one direction only. 3 shows the direction in which the current flows. 4. The arrowhead points in the direction of current flow. While the anode and cathode are indicated here, they are not usually indicated in circuit diagrams. 4 Question In a diode, does current flow from anode to cathode, or cathode to anode? Answer Current flows from anode to cathode. 4.
