Most modern TV's draw power even if turned off. The circuit the power is used in does what function?
- A.
Sound
- B.
Remote control
- C.
Color balance
- D.
High voltage
Correct Answer
B. Remote controlExplanation
Most modern TVs draw power even if turned off in order to keep the remote control function active. The remote control operates through infrared signals that require a small amount of power to be constantly supplied to the TV. This allows the user to turn on the TV using the remote control, even when it is in standby mode.Rate this question:

Which is a type of Electrically-Erasable Programmable Read-Only Memory?
- A.
Flash
- B.
Flange
- C.
Fury
- D.
FRAM
Correct Answer
A. FlashExplanation
Flash is a type of Electrically-Erasable Programmable Read-Only Memory (EEPROM). It is a non-volatile memory technology that can be electrically erased and reprogrammed. Flash memory is commonly used in devices such as USB drives, solid-state drives, and memory cards. It offers high storage capacity, fast read and write speeds, and low power consumption, making it suitable for a wide range of applications.Rate this question:

The purpose of choke in tube light is ?
- A.
To decrease the current
- B.
To increase the current
- C.
To decrease the voltage momentarily
- D.
To increase the voltage momentarily
Correct Answer
D. To increase the voltage momentarilyExplanation
The purpose of a choke in a tube light is to increase the voltage momentarily. A choke is an inductor that stores energy in its magnetic field when the current passes through it. When the current is interrupted, the choke releases the stored energy, causing a momentary increase in voltage. This voltage spike helps to initiate and maintain the ionization process in the tube light, ensuring that it starts and operates efficiently.Rate this question:

Who is largely responsible for breaking the German Enigma codes, created a test that provided a foundation for artificial intelligence?
- A.
Alan Turing
- B.
Jeff Bezos
- C.
George Boole
- D.
Charles Babbage
Correct Answer
A. Alan TuringExplanation
Alan Turing is largely responsible for breaking the German Enigma codes during World War II. He developed a machine called the Bombe that helped decipher the encrypted messages. Turing's work in codebreaking laid the foundation for modern cryptography and also contributed to the development of artificial intelligence. His concept of the "Turing Test" is a test to determine a machine's ability to exhibit intelligent behavior, which is a fundamental concept in the field of AI.Rate this question:

Made from a variety of materials, such as carbon, which inhibits the flow of current...?
- A.
Choke
- B.
Inductor
- C.
Resistor
- D.
Capacitor
Correct Answer
C. ResistorExplanation
A resistor is made from a variety of materials, such as carbon, which inhibits the flow of current. This means that when current passes through a resistor, it encounters resistance, causing a drop in voltage and limiting the flow of current. Therefore, a resistor is the correct answer in this context.Rate this question:
