Taught: Semester 2 (Jan to Jun) View Timetable

Year running 2023/24

### Pre-requisite qualifications

GCSE in Mathematics and Science-Physics or GCSE in Mathematics and Science Double Award.

Module replaces

PHYS0035 Thermodynamics and Electromagnetism

This module is not approved as a discovery module

### Module summary

This module is designed for students who have not had the opportunity of an A level education in Physics and can teach you Physics to A level equivalent standards. The only prerequisite is GCSE level mathematics, or equivalent. PHYS0036 (Fields and Electricity) concerns the essentials of fields (gravity and electromagnetic) and electricity.

### Objectives

On completion of the module students should be able to:

- perform calculations involving electrostatic force and electrostatic potential
- contrast the concepts of gravitational and electrostatic fields
- perform calculations involving inverse square laws of fields
- understand circular motion in its application to orbiting bodies
- carry out calculations relating voltage, current and power in simple DC circuits
- use the relationships between charge, voltage and capacitance of a capacitor
- recall that moving charges give rise to magnetic effects
- carry out calculations involving the force on a moving charge or current in a magnetic field
- carry out calculations involving magnetic fields produced by currents
- describe the laws of electromagnetic induction
- perform calculations involving emfs produced by changing magnetic fields
- recall the ideas concerning alternating currents
- carry out calculations on capacitors, inductors and transformers

This module forms part of a package of three modules (PHYS0016, PHYS0025 and PHYS0036) which will prepare students for entry to the level 1 Physics component of an appropriate degree programme and in conjunction with suitable modules at the same level in other subjects will prepare students for entry to a level 1 Engineering degree.

Learning outcomes
