A student investigates how the resistance of a light-dependent resistor (LDR) changes with light intensity.
The student has:
- a 6.0 V d.c. power supply
- a 150 Ω fixed resistor
- an LDR labeled Component Y.
The student wants to measure the potential difference (voltage) across Component Y and the current through the circuit.
Figure 1 shows the circuit that the student connected.
The circuit is connected incorrectly.
Describe how the student should correct the mistake (or mistakes) to make the circuit function properly.
