Product Overview
The Resistance Box 500 Ohms is designed for educational electrical experiments where a known resistance is introduced into a circuit. It helps students observe how changing resistance affects current and voltage under controlled laboratory conditions.
Depending on the supplied configuration, resistance selection may use interchangeable plugs or another mechanism. It can support practical activities involving Ohm's law and basic circuit measurements when paired with compatible electrical instruments. Contact PSAW Laboratory Equipments to verify the actual model and included components before ordering.
Applications in Physics Laboratories
Ohm's Law Experiment
Introduce known resistance values into a suitable circuit and observe the corresponding current and voltage readings.
Electrical Circuit Practicals
Help learners investigate how resistance influences circuit behaviour with a suitable power source and measuring instruments.
Resistance Measurements
Use known resistance values as part of suitable measurement exercises and compare calculated and observed results.
Science Education
Support supervised physics demonstrations in schools, colleges, training institutions and educational laboratories.
How to Use a Resistance Box
- Inspect the instrument and identify its terminals and resistance-selection mechanism.
- Switch off the circuit supply before connecting or changing the resistance setting.
- Connect the resistance box into the circuit according to the experiment diagram.
- Select the required resistance value within the verified range of the supplied model.
- Connect suitable measuring instruments, such as an ammeter and voltmeter, where required.
- Apply an appropriate laboratory supply and record the readings under instructor supervision.
- Switch off the supply before changing connections or resistance settings, and compare results with the experiment's theory.
Do not exceed the instrument's rated current or power dissipation. Confirm the manufacturer's operating limits before use.
Understanding Ohm's Law
Ohm's law describes the relationship between voltage, current and resistance for an ohmic conductor under suitable constant physical conditions.
V = I × RHere, V represents voltage in volts, I represents current in amperes and R represents resistance in ohms. A resistance box can provide known resistance values for a suitable experiment.
