Difference between ldr and fixed resistor

WebConnect a voltmeter in parallel with the LDR to measure the potential difference across it. Use a variable resistor in series with the LDR to vary the potential difference across the LDR. Cover the LDR so that very little light reaches its surface. Start with a potential difference of zero and increase the potential difference by an interval of ... WebThe fixed resistor and the “loop” are connected in series with each other. This means that the source potential difference (PD from the power supply) will be shared out between the fixed resistor and the “loop”; V total = V 1 + V 2.With series circuits, the potential difference is shared out based on the component’s resistance; components with a …
