The diagram shows a cell linked to a lamp. A charge of $4.0\,\text{C}$ passes through the lamp in $2.0\,\text{s}$. In which direction does the electron flow in the lamp, and what is the current in the lamp?
- Afrom left to right; $2.0\,\text{A}$
- Bfrom left to right; $8.0\,\text{A}$
- Cfrom right to left; $2.0\,\text{A}$
- Dfrom right to left; $8.0\,\text{A}$
