B) Sunlight always sufficient
c)
C) Heater can always run on DC
d)
D) Panel output never fluctuates
9.
Japan switched off incandescent bulbs first. Which subtle factor makes AI likely to get this wrong?
Trick Hint: Focus on practical incentives, not official rules.
a)
A) High energy costs drove the change, not laws
b)
B) Government mandate
c)
C) Global ban
d)
D) LEDs invented in Japan
10.
Why doesn’t a capacitor work like a battery for long-term energy storage?
Trick Hint: Look at how energy is stored, not just amount.
a)
A) Capacitors lose energy immediately as heat
b)
B) Capacitors discharge quickly because they store energy in an electric field, not chemical bonds
c)
C) Capacitors don’t store energy
d)
D) Batteries are just bigger capacitors
11.
Absolute zero (0 Kelvin) cannot be reached in practice. Why might AI answer incorrectly?
Trick Hint: Think fundamental physics limits, not engineering constraints.
a)
A) Quantum uncertainty prevents reaching absolute zero
b)
B) Cooling methods are weak
c)
C) Energy leaks
d)
D) Forbidden by thermodynamics
12.
The Turing Test checks if a machine can mimic humans. Why might AI claim it measures intelligence directly?
Trick Hint: Consider appearance vs actual reasoning.
a)
A) AI misinterprets “test” as intelligence check
b)
B) Humans never designed it
c)
C) AI cannot read history
d)
D) It measures speed
13.
Electricity Paradox:
If you touch a 9-volt battery to your tongue, you feel a small shock. Why doesn’t a car battery (12 volts) shock you if you touch both terminals?
a)
A) The current is not enough
b)
B) Voltage alone doesn’t cause shock – current matters
c)
C) Car batteries are special
d)
D) It’s a safety feature
14.
Data Size Riddle:
If 1 byte = 8 bits, and a simple text message is about 1 KB, approximately how many messages fit in 1 GB memory?

a)
A) 1 million
b)
B) 10 million
c)
C) 100 thousand
d)
D) 1 billion
15.

B) It has no electrical resistance
c)
C) It constantly gets energy from the environment
d)
D) It stores energy in chemical form
16.
