1. A voltmeter must be installed in (series or parallel) with the component whose voltage is to
be measured.
2. An ammeter must be installed in (series or parallel) with the component whose current is to
be measured.
The two most widely used secondary cells are:
3.
4.
5. The electrolyte used in a lead-acid cell is a solution of
acid and water.
6. The specific gravity of the electrolyte in a lead-acid cell (is or is not) an indication of the
state of charge of the cell.
7. The open-circuit voltage of a lead-acid cell is approximately
volts.
8. Spilled electrolyte from a lead-acid battery is neutralized with a solution of
and water.
9. The positive plate of a nickel-cadmium cell is made of
.
10. The negative plate of a nickel-cadmium cell is made of
.
11. The electrolyte used in a nickel-cadmium cell is
water.
and
12. The specific gravity of the electrolyte in a nickel-cadmium cell (is or is not) an indication of
the state of charge of the cell.
13. The open-circuit voltage of a nickel-cadmium cell is
volts.
14. Spilled electrolyte from a nickel-cadmium battery is neutralized with a solution of
and water.
15. The freezing temperature of the electrolyte in a fully charged lead-acid battery is (higher or
lower) than it is for the electrolyte in a discharged battery.
16. The voltage drop across a forward-biased silicon diode is approximately
volts.
17. A zener diode is (forward or reverse) biased when it is used as a voltage sensor.
18. Load current (does or does not) flow in a bipolar transistor circuit when no base current is
flowing.
19. Emitter-collector current (does or does not) flow in an NPN transistor when its base is
negative with respect to its emitter.
20. Current (does or does not) have to flow into or out of the gate of a field effect transistor for it
to conduct.
21. A light emitting diode produces light when it is (forward or reverse) biased.
