A light-dependent resistor is connected across a supply. The readings for the light-dependent resistor are shown in the table.
| Quantity | Value |
|---|---|
| Potential difference across the light-dependent resistor | 6.0 V |
| Current through the light-dependent resistor | 15 mA |
Use these measurements to determine a value for the light-dependent resistor’s resistance.
