Question 1

What is Electric Charge?

Answer 1

it is a property of matter by which it attracts or repels other matter placed in an electromagnetic field.

Question 2

What is Electric charge denoted by?

Answer 2

‘Q’

Question 3

What is the S.I unit of Electric Charge?

Answer 3

Coulomb

Question 4

1 mC is equal to?

Answer 4

10^-3 C

Question 5

1microcoulomb is equal to?

Answer 5

10^-6 C

Question 6

what is the electronic charge of one electron?

Answer 6

1.6*10^-19 C

Question 7

what is the formula of net charge?

Answer 7

Q=ne (n is no of electrons, e is electronic charge)

Question 8

What is Electric Current?

Answer 8

Rate of flow of charge is electric current

Question 9

What is the formula of Electric Current

Answer 9

I = Q/T

Question 10

what does ‘I’ denote?

Answer 10

current

Question 11

what does Q denote?

Answer 11

amount of charge/ charge

Question 12

what does t denote?

Answer 12

time

Question 13

what is the s.i unit of current

Answer 13

Ampere

Question 14

s.i unit of charge

Answer 14

coulomb

Question 15

What is conventional current?

Answer 15

Conventional Current assumes that current flows out of the positive terminal, through the circuit and into the negative terminal of the source. This was the convention chosen during the discovery of electricity. (opposite to the flow of e- ions)

Question 16

what is electric potential?

Answer 16

electric potential is the amount of work needed to move a unit positive charge from a reference point to a specific point inside the field without producing any acceleration.

Question 17

how is electric potential dentoted?

Answer 17

V

Question 18

what is voltage?

Answer 18

Voltage can be defined as the electric potential between two points

Question 19

delta V =

Answer 19

V= W/Q

Question 20

what is S.I unit of electric potential?

Answer 20

Volts

Question 21

S.I unit of work done

Answer 21

Joule

Question 22

s.i unit of charge

Answer 22

coulomb

Question 23

define 1v of potential difference.

Answer 23

The potential difference between two point is said to be 1 volt if 1 Joule of work is done in moving a positive change of 1 Coulomb from one point to the other against the electrostatic force.
