Answer:
The current passing through it is 8 A.
Explanation:
given:
work done W = 4000 J
charge q = 10 C
resistance R = 50 Ω
we know that ,
W = V q
V = W/q
V = 4000 / 10
V = 400 V
According to Ohm's law,
current I = V/R
I = 400/50
I = 8 A
therefore the current in the circuit is 8 A.
Hope it helps !

Given:
- Work done to transfer 10 C charge is 4000 Joule.
- Resistance in circuit is 50 Ohm.
To find:
- Current in circuit ?
Calculation:
First of all, let's find out the potential difference in the circuit across the resistor !
- Potential difference is defined as the amount of work done to transporter unit positive charge across two different points in an electric field.
Let potential difference be V :
Now, the current in the circuit will be :
So, current in circuit is 8 Ampere .
