Physics Investigating RC Circuit Time Constants: Pre-Lab Notes, Teacher Notes and Technician Guide

This pre-lab resource prepares students for a practical investigation of the time constant in RC (resistor–capacitor) circuits. It provides structured guidance on the core ideas, apparatus, measurements and safety points needed before laboratory work begins.

Keeping it Simple
This pack introduces RC circuit behaviour in a clear, manageable way. It focuses on what students must understand and do: how a capacitor charges and discharges through a resistor, how voltage changes with time, and how the time constant is determined from data.

What’s Included in This Pre-Lab Pack

  1. Student Pre-Lab Notes

Clear explanation of RC circuits and exponential charging/discharging

Definition of the time constant (τ = RC) and what it represents

Diagram of a typical setup (power supply, resistor, capacitor, switch, voltmeter or data logger)

Step-by-step outline of the procedure and how to record voltage vs time

Guidance on identifying variables and keeping conditions consistent

Worked examples showing how to estimate τ from graphs

Prompts for plotting voltage–time graphs and recognising exponential trends

Notes on uncertainty and error sources (connection resistance, timing delay, instrument response)

Safety reminders for electrical equipment and secure connections

Short exam tips linked to exponential graphs and circuit behaviour

  1. Teacher Notes
    Background theory linking RC behaviour to exponential change

Suggested pre-lab questions to check understanding

IB DP Physics 12 Practical Investigations Pre-Lab Notes Bundle 2026

IB DP Physics Practical Investigations: Pre-Lab Notes, Teacher Notes and Technician Guides Bundle This bundle brings together a collection of IB DP Physics pre-lab note packs designed to support students and staff before practical investigations. Each resource follows a consistent structure so students know what to expect and teachers and technicians can prepare laboratory work efficiently and safely. **Keeping it Simple** These pre-lab packs are built for clarity. Each investigation gives students a short conceptual overview, clear expectations, and practical guidance before they enter the lab. The focus is on understanding the aim, recognising key variables, and knowing how measurements and analysis will be carried out. **What This Bundle Provides** Each practical includes three core components: 1. Student Pre-Lab Notes Clear explanations of the main physics concepts for each investigation Diagrams of typical apparatus and setups Step-by-step outlines of procedures and data collection Guidance on variables, measurements and basic calculations Prompts for graphing and interpreting results Notes on uncertainty and common sources of error Safety reminders relevant to the apparatus used Short exam tips linked to practical skills and data analysis 2. Teacher Notes Concise background theory for pre-lab discussion Suggested concept-check questions Common student misconceptions to address Differentiation ideas for varied confidence levels Assessment opportunities linked to reasoning and data interpretation 3. Technician Preparation Guides Equipment and materials lists Setup guidance for safe, organised stations Health and safety reminders Assembly notes for consistent apparatus arrangement Troubleshooting tips for common technical issues Investigations Included This bundle covers a wide range of IB DP Physics practical themes, including: Mechanics (free-fall, Atwood machine, Young’s modulus) Waves and optics (double slit, refraction, polarization, speed of sound) Electricity and circuits (internal resistance, RC time constants) Thermal physics (specific heat capacity, gas laws) Nuclear physics (radioactive decay and half-life) **Audio Support** Each pack includes a short audio summary Explains the aim, setup and analysis in accessible language Useful for pre-lab preparation or revision Ideal For IB DP Physics teachers organising practical programmes Students who benefit from structured pre-lab preparation Laboratory technicians needing clear setup and safety guidance This bundle provides a consistent framework for preparing students for practical work while supporting safe practice and clear understanding of measurement and analysis.
