, are represented by straight lines passing through the origin on the same

V

–

I

graph. The slope of the line for wire

P

is twice the slope of the line for wire

Q

6\,\text{V}

is applied across each wire, what is the ratio of currents

I_P : I_Q

flowing through them? (a)

2:1

(b)

4:1

(c)

1:2
