The $I$-$V$ characteristics for two electrical components P and Q are displayed. Which statement is correct?
- AFor a current of $0.5\,\text{A}$, the power dissipated in Q is double that in P.
- BFor a current of $1.9\,\text{A}$, the resistance of Q is approximately half that of P.
- CThe resistance of Q increases as the current in it increases.
- DP is a fixed resistor and Q is a filament lamp.
