Question

what is the potential diffrance when 5c of charge is passed across and work is done is 45j

Answer 1

Answer:

9 volts

Explanation:

potential difference = Work done/ Charge

potential difference = 45/5

potential difference = 9 Volts

Answer 2

Required Answer:-

The above question is just a "Apply formula-get answer" type question. We know that:

• Potential difference between any points is the work done by moving an unit charge from one point to another.

It is given by:

$\huge{ \boxed{ \sf{ \orange{V = \frac{W}{Q}}}}}$

Now just plugging the values of work done and charge to get the potential difference:

⇒ V = 45 J / 5 C

⇒ V = 9 J/C or 9 V.

And we are done! :D

Often we are confused between the terms emf and potential difference. They are defined as:

Emf: It is the maximum potential difference between any two electrodes or points when no current is drawn through i.e. in a open circuit.

Potential difference: It is the difference in the potentials of any two points around a closed circuit.
