Look at Figure and state the direction of the conventional current in the electrolyte (towards the left, towards the right or in both directions at the same time?).

Figure shows a circuit with a conducting solution having both positive and negative ions.

Copy the diagram and draw in a cell between points A and B. Clearly indicate the positive and negative terminals of the cell.

Figure shows a circuit with a conducting solution having both positive and negative ions.

Add an arrow to show the direction of the conventional current in the solution.

Add arrows to show the direction of the conventional current in the connecting wires.

A car battery is labelled $\text{'}50\mathrm{Ah}\text{'}$. This means that it can supply a current of $50 \mathrm{A}$ for one hour

(a) For how long could the battery supply a continuous current of 200 A needed to start the car?
