Question

estimate the work to be done when 30c of charge flows for a potential difference of 30v​

Answer 1

Explanation:

answer is mentioned above

Answer 2

Answer:

The work to be done when 30c of charge flows for a potential difference of 30v​ will be $900\ J$

Explanation:

• The potential energy per unit charge is defined as electric potential.

• Let E be the  energy, V be the potential and Q be the charge, then the electric potential is,

                 $V = \frac{E}{Q}$         ...(1)

• The energy available for $30\ C$ charge is equivalent to the work done by the$30\ C$ charge.
• Let W be the work done, then the equation (1) becomes,

                 $V = \frac{W}{Q}$        

         Or   $W =VQ$     ...(2)    

In the question, it is given that,

$V = 30\ V$

$Q = 30\ C$

By using equation (2),

$W =30\times30 = 900\ J$
