Ohm's Law Demonstration Equipment

Product Code : SCL-EAE-11182

The Ohm’s Law Demonstration Equipment is a current-electricity laboratory apparatus used to demonstrate the relationship between voltage, current, and resistance in a low-voltage circuit. It supports V-I graph plotting, resistance calculation, circuit connection practice, and classroom demonstrations for schools, colleges, polytechnics, ITI/TVET centres, STEM labs, and procurement buyers.

Product Description

The Ohm’s Law Demonstration Equipment from Lab Equipments Ambala is best positioned under Physics Lab / Electrical and Electronics / Current Electricity Apparatus. A dedicated product page with final product code, meter type, supply range, resistor values, rheostat rating, terminal layout, protection, accessories, and documentation should be confirmed before publishing.

Ohm’s Law demonstration equipment helps learners apply a measured voltage across a resistor, measure the resulting current, and verify that current is proportional to voltage when resistance remains constant. It is used to build the basic experimental foundation for resistance measurement, series circuit wiring, meter placement, and electrical measurement practice.

Key Features

• Ohm’s Law demonstration: supports practical observation of the voltage-current-resistance relationship.
• V-I graph activity: helps students record voltage and current values and plot the linear response of a resistor.
• Current-electricity learning: suitable for experiments using DC supply, resistor, rheostat, ammeter, voltmeter, key, and connecting leads.
• Resistance calculation: enables learners to calculate resistance from measured voltage and current readings.
• Classroom demonstration use: suitable for teacher-led practical demonstrations and supervised student laboratory work.
• Low-voltage practical setup: intended for safe educational circuit experiments when used with the confirmed supply rating.
• Specifications pending: supply type, voltage range, current range, meter type, resistor values, protection, and accessories must be verified.

How to Use the Ohm’s Law Demonstration Equipment

1. Place the equipment on a dry, stable laboratory bench.
2. Confirm the power-source rating, meter range, resistor value, current-control method, and wiring diagram before switching on.
3. Connect the resistor and current-control element in series with the ammeter or current display.
4. Connect the voltmeter or voltage display across the resistor under test.
5. Set the supply or control knob to the minimum output before energising the circuit.
6. Increase the voltage gradually and record the corresponding current for each setting.
7. Plot voltage against current and calculate resistance from the voltage-current ratio.
8. Switch off the supply before changing resistor values, meter ranges, or circuit connections.

Safety note: Use the Ohm’s Law Demonstration Equipment only with the confirmed low-voltage DC supply. Do not connect the apparatus directly to mains supply. Keep terminals dry, use correct meter polarity and range, avoid short circuits, switch off before rewiring, and conduct experiments under instructor or laboratory technician supervision.

Care & Maintenance

• Keep the panel, terminals, switches, meters, resistor section, and connecting leads clean and dry.
• Inspect leads, sockets, fuses, meter operation, resistor condition, and supply output before each experiment.
• Do not exceed the confirmed voltage, current, resistance, power, or meter-range limits.
• Store the equipment in a dry, dust-controlled cabinet after use.

Frequently Asked Questions

What is Ohm’s Law Demonstration Equipment used for?

Ohm’s Law Demonstration Equipment is used to show the relationship between voltage, current, and resistance, record V-I readings, plot a V-I graph, and calculate resistance in a low-voltage circuit.

Does this equipment include a power supply?

The inclusion of a power supply is not verified for this product name. Confirm whether the final product includes a built-in DC supply, external adapter, battery eliminator, or requires a separate laboratory power supply.

What readings are recorded during the experiment?

Students record voltage across the resistor and current through the circuit at multiple settings. These readings are used to plot the V-I graph and calculate resistance.

Is this suitable for school physics labs?

Yes. It is suitable for school physics labs, STEM classrooms, electronics labs, polytechnics, and introductory engineering practicals when used with the confirmed low-voltage DC supply.

Can this equipment be connected directly to mains power?

No. The apparatus should be used only with the confirmed low-voltage DC supply or approved adapter. Direct mains connection can damage the apparatus and create an electrical hazard.

What should be confirmed before ordering?

Confirm product code, power-source type, voltage range, current range, meter arrangement, resistor values, rheostat or current-control section, protection, connecting leads, manual, packing, and documentation.
