Comparator Quiz

Consider the circuit diagrams of four different comparator circuits. To answer the questions you will also need to know about the characteristics of an LDR and how potential dividers work.

When the power supply voltages are ±15 V, the output voltage, Vout is ±13 V.

When the power supply voltages are +9 V and 0 V, the output voltage, Vout is +7 V or +2 V.
