As a petrol car is being refuelled, it receives $50$ litres of fuel in $90$ seconds. Each litre of petrol contains $34\,\text{MJ}$ of energy. If an electric car is to obtain the same total energy in the same period from a $230\,\text{V}$ supply, what minimum current is needed?
- A$2700\,\text{A}$
- B$8.2 \times 10^4\,\text{A}$
- C$7.4 \times 10^6\,\text{A}$
- D$6.6 \times 10^8\,\text{A}$
