ORT Physics case studies

ORT Physics · Put your knowledge to work in context.

The ORT Physics examination is a subject assessment for candidates who need to demonstrate working competence in physics at the level taught in post-16 or early undergraduate programmes. It is typically taken by students preparing for university entrance or by candidates who need a standalone physics credential for further study or employment. The exam is delivered in multiple-choice format and samples across six broad areas: mechanics and motion, thermodynamics and kinetic theory, electricity and magnetism, optics, and atomic and nuclear physics, with a final section on laboratory methods and data analysis. Questions tend to test reasoning rather than recall alone, so expect to combine a formula with a physical interpretation, read a description of an experiment and judge what it establishes, or spot which assumption a calculation depends on. The ORT Physics case studies are 5 cases and about 3,360 words.

Loaded Voltage Divider for a Data Logger

An engineer is connecting a 12.00 V reference supply across a two-resistor divider to scale a signal for a data logger. R1 = 1.00 MΩ from +12 V to the output node; R2 = 2.20 MΩ from the output node to ground.
