Calculate the current through the resistor with resistance $5800\,\Omega$.
Calculate the thermistor resistance.
The battery initially stores $2.6 \times 10^{4}\,\text{J}$. Assume the battery e.m.f. stays constant. Determine the final energy stored in the battery after a charge of $330\,\text{C}$ has passed through it.
The surroundings change so that the thermistor’s resistance increases. State whether the thermistor’s temperature decreases, increases, or stays unchanged.
The surroundings change so that the thermistor’s resistance increases. State whether the current in the thermistor decreases, increases or remains unchanged.
The surroundings change so that the thermistor’s resistance increases. State whether there is a decrease, increase or no change to the potential difference across the thermistor.
The surroundings change so that the thermistor’s resistance increases. State whether there is a decrease, increase or no change to: (i) the temperature of the thermistor (ii) the current in the thermistor (iii) the potential difference across the thermistor.
