This video introduces physiotherapy students to the fundamentals of static electricity, including how charges build up and interact on non-conductive surfaces. You will learn key theoretical concepts such as electric fields, lines of force, and potential differences, which are essential for understanding electrotherapy modalities.
What you’ll learn?
- What is Static Electricity?
- Current Electricity vs Static Electricity
- Properties of Static Electricity
- Charged Bodies & Electric Field
- Properties of Lines of Force
- Lines of Force in Conductors vs Insulators
- Introduction to Potential & Capacitance
These basic electrical principles are the foundation for every electrotherapy modality you’ll study next — including therapeutic ultrasound, which converts electrical energy into mechanical sound waves for tissue healing.
