The input voltage is $6.0\,\text{V}$. Fill in Table 8.1 to indicate the output voltage for the different resistor values of the two resistors.
(b(i))[1]
In the space below, sketch the circuit symbol for an LDR.
(b(ii))[1]
State what happens to the resistance of the LDR and the output voltage when the LDR is moved from darkness into daylight.
(b(iii))[1]
State the name of the component used in place of the LDR to produce an output voltage that varies with temperature.
