MP Vyapam Electrical - Sub Engineer Mock Test - 7 - Question 1

The instrument _________ is used for detecting electric current is

Detailed Solution for MP Vyapam Electrical - Sub Engineer Mock Test - 7 - Question 1

CONCEPT:

Galvanometer:

A galvanometer is used for detecting current in an electric circuit.
The galvanometer is the device used for detecting the presence of small currents and voltage or for measuring their magnitude.
The galvanometer is mainly used in the bridges and potentiometer where they indicate the null deflection or zero current.
The potentiometer is based on the premise that the current sustaining coil is kept between the magnetic field experiences a torque.

EXPLANATION:

From the above, it is clear that the galvanometer is the instrument used for detecting the presence of electric current in a circuit. Therefore option 1st is correct.

Additional Information 

Mistake Point
Difference between Ammeter and Galvanometer:

The ammeter shows only the magnitude of the current.
The galvanometer shows both the direction and magnitude of the current.

Detailed Solution for MP Vyapam Electrical - Sub Engineer Mock Test - 7 - Question 2

Key Points

 Indian single integrated judicial system, the high court operates below the Supreme Court but above the subordinate courts.
The judiciary in a state consists of a high court and a hierarchy of subordinate courts. The high court occupies the top position in the judicial administration of a state.
The institution of the high court originated in India in 1862 when the high courts were set up at Calcutta, Bombay and Madras 1 . In 1866, a fourth high court was established at Allahabad.
In the course of time, each province in British India came to have its own high court. After 1950, a high court existing in a province became the high court for the corresponding state.
The Constitution of India provides for a high court for each state, but the Seventh Amendment Act of 1956 authorized the Parliament to establish a common high court for two or more states or for two or more states and a union territory.
The territorial jurisdiction of a high court is co-terminus with the territory of a state. Similarly, the territorial jurisdiction of a common high court is co-terminus with the territories of the concerned states and union territory.
