In the circuit shown, the current in the $$8\,\Omega$$ resistance across G and H is $$i=0.5\,\text{A}$$. The ammeter is ideal. The internal resistance of the cell is $$0.8\,\Omega$$. Choose correct option(s).

A

Reading of the ammeter is $$1.5\,\text{A}$$

B

Potential difference across A and H is $$13\,\text{V}$$

C

Potential difference across C and F is $$9\,\text{V}$$

D

The emf of the cell is $$24\,\text{V}$$
