Given network of $$18$$ resistors, each equal to $$R=3\,\Omega$$, is connected in series with resistor $$R_0$$ to a source of emf $$9\,\text{V}$$. Choose the correct options.

A

Current drawn from battery is $$1.5\,\text{A}$$

B

Potential difference between A and B is $$7.5\,\text{V}$$

C

Electrical power dissipated in $$R_0$$ is $$2.25\,\text{W}$$

D

Electrical power dissipated in network between A and B is $$12.25\,\text{W}$$
