Ohm’s Law Experimental Kit with Integrated Power Supply

Product Description

The STEMAids Ohm’s Law Experimental Kit combines a circuit experiment platform with an integrated electrical power supply. Students vary the applied voltage across a suitable resistive component, measure the resulting current and compare the observations with the relationship between voltage, current and resistance.

The integrated configuration reduces the need to arrange a separate power source for every practical session. It supports structured data collection, graph plotting and resistance calculation while helping students learn correct ammeter and voltmeter connections. Exact supply and meter specifications must be confirmed before use.

Key Features

• Integrated power supply: Provides the circuit source within the experimental unit, subject to the confirmed output specification.
• Direct Ohm’s law verification: Supports measurement of voltage and current across a resistive load.
• Structured circuit layout: Helps students identify the power source, load and measurement connections.
• Quantitative experiment: Enables observation tables, resistance calculations and voltage–current graphs.
• Reusable laboratory platform: Suitable for repeated supervised practical sessions.
• Reduced setup complexity: Limits the number of separate instruments required where meters are built into the supplied unit.
• Curriculum-focused design: Supports electricity, resistance, circuit measurement and graphical-analysis lessons.

How to Use the Ohm’s Law Experimental Kit with Integrated Power Supply

1. Inspect the unit, terminals, leads and power cable for damage.
2. Keep the integrated supply switched off and set its output to minimum.
3. Connect the ammeter in series with the resistive load.
4. Connect the voltmeter in parallel across the resistive load.
5. Ask the instructor to verify the circuit before energising it.
6. Switch on the supply and increase the output gradually within the confirmed ratings.
7. Record corresponding voltage and current values at several settings.
8. Switch off the supply, calculate resistance and plot the required graph.

Safety note: Do not alter connections while the circuit is energised. Avoid short circuits, observe meter polarity and ratings, and operate the integrated supply only from the approved input source under trained supervision.

Care & Maintenance

• Switch off and disconnect the unit before cleaning or storage.
• Keep the panel, terminals and ventilation openings dry and free from dust.
• Do not pull leads by their cables or force incompatible plugs into terminals.
• Check supply output and meter performance periodically against suitable reference instruments.

Frequently Asked Questions

What does the Ohm’s Law Experimental Kit demonstrate?

It demonstrates the relationship between voltage, current and resistance by measuring current through a resistive load at different applied voltages.

Does the kit have a built-in power supply?

Yes. An integrated power supply is confirmed by the product name. Its output range, regulation and protection features require verification.

Are the ammeter and voltmeter built into the kit?

The meter configuration is not confirmed. Check whether the selected model has integrated analogue meters, digital meters or connections for external instruments.

How is Ohm’s law verified experimentally?

Record voltage and current at several settings while the conductor’s physical conditions remain reasonably stable. A linear voltage–current relationship indicates approximately constant resistance.

Can students calculate resistance with this kit?

Yes. Resistance can be calculated from each measured voltage and current pair, or derived from the slope of the appropriate graph.

Can the integrated supply be connected to any mains voltage?

No assumption should be made about the input voltage. Use only the mains input and frequency stated on the product label or approved specification.
