Study Notes
Experiment Overview
- Objective: Investigate the relationship between Plate current and solenoid current.
- Process involves systematically altering Plate Voltage during experimentation.
Data Collection
- Record Plate current (Ia) values while varying Plate Voltage.
- Note that Plate current should be significantly reduced before analyzing results.
Graphing
- Create plots to illustrate the relationship between Plate current (Ia) and solenoid current for each Plate Voltage.
- Ensure each plot showcases the intersection between the tangent of the curve and the steady Ia value.
Critical Current Determination
- Identify the critical solenoid current by focusing on the plot's tangent's intersection.
- This critical current corresponds to lower magnetic field values (denoted as H).
Calculation of Hc
- From the established critical current (He), derive the Hc value.
- Use the appropriate relation/formula to calculate Hc based on critical conditions noted in the experiment.
