This document contains a 10 question basic electronics quiz with answers. It covers topics like batteries, ammeters, short circuits, component sizes, charge interactions, schematic diagrams, the differences between fuses and circuit breakers, how primary and secondary cells generate DC, the function of switches, and materials that oppose electron movement. The questions test fundamental electronics knowledge and are answered with brief explanations of the correct responses.

1. Basic electronics quiz part 3

2. 1. A lead-acid battery is an example of a
A.solar cell
B.fuel cell
C.primary battery
D.secondary battery

3. Ans D.secondary battery
Primary battery - It can be used
once.Secondary battery - It can be used
several times(Charge & Discharge able
once)so lead - Acid battery is secondary
battery. It can be rechargable once.

4. – 2. An ammeter is used to
measure
– A.voltage
– B.current
– C.resistance
– D.All of the above

5. – Ans B.current
– Ammeter is an electronics
measuring device which
can measured the ampere.
Then ampere is the
stander unit of CURRENT.

6. – 3. A short circuit will have:
– A..a small current flow
– B.a large current flow
– C.no current flow
– D.some current flow

7. – Ans B.a large current
flow
– Short circuit means r=0. So
if r is 0 that means i-maxm,
so B.

8. – 4. Which is the smallest?
– A.atom
– B.proton
– C.neutron
– D.electron

9. Ans D.electron
mass of proton &
neutron =
1.678*10^-27.while
that of electron is =
9.1*10^-31.

10. – 5. Which of the following statements is
true?
– A.Unlike charges repel and like
charges attract.
– B.Like charges repel and unlike
charges attract.
– C.Unlike charges attract and like
charges attract.
– D.Like charges repel and unlike
charges repel

11. Ans B.Like charges repel and
unlike charges attract.
Same direction charges always
reple like N&N and oppose
charges attract like N&S.

12. 6. What do you call a diagram that shows the
electrical connections of a circuit's components?
A.A schematic diagram
B.A pictorial diagram
C.A block diagram
D.An electrical diagram

13. – Ans A.A schematic
diagram

14. 7. The basic difference between a fuse and a circuit
breaker is
A.a fuse is slower
B.a fuse is reusable
C.a circuit breaker is reusable
D.a circuit breaker is more reliable

15. Ans C.a circuit breaker is reusable
Fuse gets burnt when any short or large current
flows, so it cannot be reused (no question of reuse)
, whereas CB just trips when a short occurs, so it
can be reused by turning it to the initial position.

16. 8. A secondary cell generates dc via chemical activity; a
primary cell generates dc:
A.electrically
B.thermally
C.optically
D.chemically

17. Ans D.chemically
Primary batteries can be used once because the
chemical reactions that supply electrical current are
Irreversible. In secondary batteries that the
chemical reaction that supply electrical current are
readily reversed. So in both batteries chemical
reaction only takes place to generate dc.

18. 9. A switch is a device that:
A.short circuits complex circuits
B.holds a fuse
C.has double poles
D.opens or completes a current path

19. – Ans D.opens or
completes a current path
– A switch is a device that make
the contact on & off. So the
answer is correct because when
the circuit is open, no current
flowing through the circuit&
when the circuit is closed,
current flowing through the
circuit.

20. 10. Which electronics material opposes the
movement of free electrons?
A.Conductor
B.Insulator
C.Semiconductor
D.Element

21. – Ans B.Insulator
– It does not allow the
movement of electron into
it "that is why insulator".
