Summary of Video: Modul Prinsip Ampere Meter dan Volt Meter DC (Bagian 2)

This video is part of a basic Physics Practicum series focused on the principles of ammeters and voltmeters in direct current (DC) circuits. It outlines several experiments designed to measure voltage, current, and internal resistance of these instruments.

Main Ideas and Concepts:

Tools Overview:
- Digital Multimeter: Used for measuring voltage and small currents.
- Ammeter: Measures current.
- Voltmeter: Measures voltage.
- Bench Resistance and Rheostat: Used to vary resistance in experiments.
- DC Voltage Source: Provides the necessary power for the experiments.
Experiments Conducted:
- Experiment 1: Measure voltage and current simultaneously to understand the relationship between resistance, voltage, and current.
- Experiment 2: Determine the internal resistance of the Ammeter and Voltmeter using a Digital Multimeter.
- Experiment 3: Calculate the internal resistance of the Ammeter and Voltmeter using Bench Resistance.

Detailed Methodology:

Experiment 1:
- Method 1:
  - Assemble a circuit with a DC Voltage Source, Bench Resistance, Ammeter, and Rheostat.
  - Parallel the Voltmeter with the Bench Resistance.
  - Set the voltage (3-5 volts) and record current and voltage while varying Bench Resistance (e.g., 20Ω, 40Ω, up to 100Ω).
- Method 2:
  - Create a series circuit with the DC Voltage Source, Bench Resistance, Ammeter, and Rheostat.
  - Parallel the Voltmeter with standard resistance.
  - Set voltage and record current and voltage while varying Bench Resistance.
Experiment 2:
- Measure internal resistance of the Ammeter:
  - Set up a series circuit with the DC Voltage Source, Ammeter, and Rheostat.
  - Parallel the Digital Multimeter with the Ammeter.
  - Vary the DC voltage and record voltage and current.
- Measure internal resistance of the Voltmeter:
  - Set up a series circuit with the DC Voltage Source, Digital Multimeter, Voltmeter, and Rheostat.
  - Record voltage and current while varying the DC voltage.
Experiment 3:
- Measure internal resistance of the Ammeter:
  - Series circuit with DC Voltage Source, Ammeter, and Rheostat.
  - Parallel the Ammeter with the Bench Resistance.
  - Vary Bench Resistance (1Ω to 5Ω) and record data.
- Measure internal resistance of the Voltmeter:
  - Series circuit with DC Voltage Source, standard resistance, Voltmeter, and Rheostat.
  - Use larger resistances (500Ω to 2500Ω) and record data.

Conclusion:

The video emphasizes the importance of understanding the principles behind ammeters and voltmeters, as well as the methods to measure their internal resistances through practical experiments.
