# Current, voltage and resistance

### Explanation of question 7

In Fig. 1.1, the current is

1. 0.5A flowing from A, through the resistor, to B
2. 0.5A flowing from B, through the resistor, to A
3. 2A flowing from A, through the resistor, to B
4. 2A flowing from B, through the resistor, to A

The answer is :- 3

I = = 6/3 = 2A

Current flows from the positive terminal of the battery via the external circuit

to the negative terminal of the battery, i.e. from A to B.
