Digital Transistor Characteristics Apparatus
Product Code : SCL-EAE-11331
The apparatus supports the practical study of potential difference, current and resistance in a suitable electrical conductor. Its meter-based arrangement allows students to observe corresponding voltage and current readings as the applied supply or circuit resistance is changed under controlled laboratory conditions.
The Lab Exports catalogue confirms that the apparatus is designed to study and verify Ohm’s law. The meter type, measurement ranges, resistor arrangement, power source, terminal format, panel material and protective features must be confirmed from the approved technical datasheet before publication or procurement.

Applications / Uses
Verifying Ohm’s law for a suitable conductor.
Measuring current through a resistive circuit.
Measuring potential difference across a circuit load.
Plotting voltage-current characteristics from observed readings.
Calculating resistance using measured voltage and current.
Determining resistance from the gradient of a V-I graph.
Teaching series ammeter and parallel voltmeter connections.
How to Use the Ohms Law Apparatus with Meters
Place the apparatus on a clean, dry and stable laboratory bench.
Keep the power switched off and set adjustable controls to their minimum positions.
Connect the circuit according to the approved diagram.
Confirm that the ammeter is connected in series with the load.
Confirm that the voltmeter is connected in parallel across the load.
Switch on the supply and apply the lowest permitted setting.
Record the corresponding voltage and current readings.
Increase the setting in approved steps and repeat the measurements.
Calculate R = V/I or plot the readings to determine resistance.
Return all controls to minimum and switch off the apparatus.
Safety note: Do not connect an ammeter directly across the power source. Avoid short circuits, and never exceed the confirmed meter, resistor or supply ratings.
Care & Maintenance
Disconnect the apparatus from its power source before cleaning or inspection.
Clean meter faces, terminals and the panel with a soft, dry cloth.
Store the unit in a dry cabinet protected from dust, moisture and impact.
Inspect leads and terminals before each session and replace damaged parts.

Frequently Asked Questions
What is an Ohms Law Apparatus with meters used for?
It is used to measure voltage and current in a resistive circuit and verify the equation V = IR. The readings can also be used to calculate resistance and plot a V-I graph.
Which meters are used in an Ohm’s law experiment?
An ammeter measures current in series with the circuit, while a voltmeter measures potential difference across the resistive load. The supplied meter types and ranges require confirmation.
How does the apparatus verify Ohm’s law?
Students record current at several applied voltages. For an ohmic conductor at approximately constant temperature, voltage is proportional to current.
Can students calculate resistance with this apparatus?
Yes. Resistance can be calculated from R = V/I or determined from the gradient of a correctly plotted voltage-current graph.
Is it suitable for school laboratories?
Yes. It is suitable for supervised physics practicals in secondary schools, colleges, polytechnics and vocational-training laboratories.
Does it include a built-in power supply?
The accessible product information does not confirm a built-in power supply. Buyers should verify the power arrangement and input specification before ordering.
