Answer 1

Question ❶ :

›»› The commercial unit of energy is ____________

Answer :

›»› The commercial unit of energy is kilowatt-hour (kWh).

Question ❷ :

How many joule of electrical energy is transferred per second by a 6 V, 0.5 A lamp ?

Answer :

›»› 3 j/s of electrical energy is transferred per second.

Given :

• Voltage of a lamp = 6 V.
• Current flowing in lamp = 0.5 A.

To Calculate :

• How many joule of electrical energy is transferred per second.

Calculation :

As we know that

→ Electric energy = Voltage * Current

→ E = VI

→ E = 6 * 0.5

→ E = 3

Hence, 3 j/s of electrical energy is transferred per second.

Question ❸ :

›»› An electric fuse works on the:

Answer :

›»› An electric fuse works on the principal of heating of current.

Correct Question ❹ :

›»› An electric motor is a device which transforms _________

Answer :

›»› An electric motor is a device which transforms into mechanical energy.

Question ❺ :

›»› An electrical generator converts _________

Answer :

›»› An electrical generator converts into electricity.

Question ❻ :

A.d.c generator is based on the principle of ___________

Answer :

›»› A.D.C. generator is base kn the principal of electromagnetic induction.

Hence Solved !

Answer 2

Question 1 :-

• The Commercial unit of energy is ____.

Answer :-

• The commercial unit of energy is kilowatt- hour(kWh).

Question 2 :-

• How many joule of electrical energy is transferred per second by a 6 V, 0.5 A lamp ?

Answer :-

• 3j/s of electrical energy is transferred per second.

Given :-

• Voltage of lamp = 6 V
• Current flowing in lamp = 0.5 A

To Find :-

• How many joule of electrical energy is transferred per second.

Solution :-

• Electrical energy(E) = Voltage(V) × Current(I)

E = V×I

E = 6×0.5

E = 3

Hence, 3 j/s is your answer.

Question 3 :-

• An electric fuse works on the:

Answer :-

• An Electric fuse work on the principal of heating effect of current .

Question 4 :-

• An electric motor is a device which transtorms _________.

Answer :-

• An electric motor is a device which transforms into Mechanical energy.

Question 5 :-

• An electrical generator converts _________.

Answer :-

• An electrical generator converts into electricity.

Question 6 :-

• A.d.c generator is based on the principle of ___________

Answer :-

• A.d.c generator is based on the principle of electromagnetic induction.
