A thermistor has a resistance of $10\text{ k}\Omega$ at $25^\circ\text{C}$ and $1\text{ k}\Omega$ at $100^\circ\text{C}$. The range of operation of is $0^\circ\text{C}$ to $150^\circ\text{C}$. The excitation voltage is $5\text{V}$ and a series resistance of $1\text{ k}\Omega$ is connected to the thermistor. The power dissipated in the thermistor is}
Show Hint
For maximum power transfer in a series circuit, the load resistance must equal the source resistance.
Here, the peak possible power is $6.25\text{ mW}$. The only stable, high-level operational power option below this limit is $5.5\text{ mW}$.
