8. Extension: Current-Voltage Relationship for a Light Bulb $$?$$ Wire up the circuit shown (Circuit C) using a variable power supply Circuit 8 Figure 8.1: Current vs Potential Difference measurement. $$?$$ With a small voltage across the bulb (low enough that the bulb DOES NOT GLOW) measure both voltage across, and current through, the bulb. What is the resistance of the globe? Observation $$8.1$$ $$?$$ Using the ohmmeter measura tha macietansa nf a huilh $$?$$ Repeat the measurement of current and voltage but this time with a voltage of about $$2.5\mathrm{V}$$ across the bulb. Once again calculate a value for resistance of the globe. Explanation $$8.1$$
