Question

Calculate the amount of charge that flows in 200V potential difference with 20000J of
energy
​

Answer 1

S O L U T I O N :

★ Given,

• Work done (w) = 20000 J
• Potential difference (v) = 200 v

★ We need to find,

• The amount of electric charge (Q)

★ Explanation,

Formula for potential difference is given as ;

★ V = W/Q

[ Put the values ]

⇒ 200 = 20000/Q

⇒ Q = 200 × 20000

⇒ Q = 4000000 C ★

Therefore,

• The amount of electric charge is 4000000 coulomb.

For information :

⇒ I = Q/t

⇒ H = I²Rt

⇒ V = IR

Answer 2

Question :-

• Calculate the amount of charge that flows in 200V potential difference with 20000J of energy .

Answer :-

• Q = 4000000 C

Given :-

V = 200 v

W = 20000 J

Here ,

" v " = Potential Difference

" w " = Work done

Have to Find :-

Calculate the amount of charge ?

Calculations :-

We know the formula :-

V = W/Q

Here ,

" v " = Potential Difference

" w " = Work done

" Q " = Charge

Now, Substituting the values in the above formula :-

↬ 200 = 20000/Q

↬ Q = 200 × 20000

Hence ,

↬ $q$ = 4000000 C

So ,

The required Answer is = 4000000 Coulomb { Charge }

Additional Information :-

✦ What is Current ?

↠ Current is the rate at which electrons flow past a point in a complete electrical circuit. At its most basic, current = flow.

↠ It expresses the quantity of electrons (sometimes called "electrical charge") flowing past a point in a circuit over a given time.

✦ How to calculate Current ?

↠ Current is usually denoted by the symbol I. Ohm's law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm's law is I = V/R.

✦ What is the unit of Charge and Electric Current ?

↠Unit of electric charge is coulomb or C, unit of electric current is ampere or A.
