(D) Black knob
World Environmental Day is celebrated every year on:
(A) 5 May
(B) 5 June
(C) 5 July
(D) 18 July
World Environment Day is celebrated on June 5 every year to remind people to save nature and the earth by stopping their non-environmentally friendly activities. Let's know more about this day, its history, significance, and theme.
Capacity when connecting capacitors to series?
(A) neither increases nor decreases
(B) increases
(C) decreases
(D) None of the above
A capacitor stores energy in the form of an electrostatic field between its plates. Increasing the size of the plates increases the capacitance because there is more room for the electrons to escape.
Electricity is generated when the drivers rotate between the magnetic fields?
(A) Moving
(B) stable
(C) Both static and dynamic
(D) None of these
In a generator, a rotating magnetic field is used to produce electrical energy. When a conductor, such as a wire, moves through a magnetic field, a voltage is induced across the conductor. This is known as electromagnetic induction, and it is the fundamental principle behind how generators work.
The voltmeter is put into the circuit?
(A) in parallel order
(B) In series order
(C) In series-parallel order
(D) None of these
Battery's electrode?
(A) must be a semiconductor
(B) Should be the conductor of electricity
(C) Should be a good conductor of electricity
(D) None of these
