The last one is correct (D)
Answer:
Hi,
The correct answer option is; D. Most of the current will flow through one part of the circuit.
Explanation:
A short circuit is a low resistance path in an electric connection between two conductors supplying current in a circuit.
It happens when excess amounts of current flow in the power source through a 'short path'.
Short circuits occur at very high temperatures which is of course caused by the heat produced during dissipation.
An example of application of short circuit is arc welding, where heating is achieved through short circuit.
The correct answer of this question is : A) Change alternating current into direct current.
EXPLANATION :
As per the question, we are given vacuum tube. Vacuum tube can be of various types. Normally it contains two electrodes called cathode and anode which are enclosed in an evacuated glass chamber . There are also other types of vacuum tubes which contain extra electrodes like control grid .
The vacuum tube can be used as a rectifier. It means that it can be used as an electronic device which will convert alternating current into direct current. It may be a half wave rectifier or a full wave rectifier. Actually the direct current obtained during the rectification of alternating current is pulsating in nature.
Hence, the correct answer is that a vacuum tube can be used to change alternating current into direct current.
