Hidden Dangers Of Water Heater: How To Install It Safely?

Seng Kwang Tan IP4 13 Practical Electricity 0 Comments

This rather informative video uses a recent local case of electrocution as a case study and goes on to explain various practical electricity concepts such as electric faults (e.g. live wire connected to earth wire). Recommended for students learning about O-level Practical Electricity, although I would caution them that some of the dialogue is based on a layman’s understanding of how electricity works, so there are some scientific inaccuracies.

Videos on Series and Parallel Bulbs

14 Current of Electricity, IP4 12 DC Circuits, IP4 13 Practical Electricity 0 Comments

These are two videos that I made on series and parallel bulbs. The second video is specially made to highlight the increase in brightness of the remaining bulbs when one or more bulbs is removed from its socket.

What students will learn in O levels is that the brightness of the bulbs will not change as the potential difference is a constant, being the emf itself.

Based on the conflict between what is taught and what is observed, students will be led to discuss the reason why.

An educational board game for 2 or any even number of players (in 2 teams) based on the concepts of current electricity. Targeted at high school / junior college physics students, Delight is a fun way of practising the use of physics concepts such as

  1. electrical power $$P=\frac{V^2}{R}$$
  2. the potential divider rule.
  3. wires bypassing a device short-circuits it.

This game can be easily printed on A4 paper and the game pieces can be cut up for use.

Game Play

  1. This game is meant for 2 players or 2 teams of players. Each player/team has the following tiles:
    • 2 x light bulbs
    • 3 x T-shaped wires
    • 2 x crossed wires
  2. The players will take turns to place the tiles on the board.
  3. Each new tile must have at least one wire connected to an existing wire on the board.
  4. The game will end when the last tile has been placed on the board.
  5. The person with the brightest bulb will win.In the event that there is an equal number of opposing bulbs of the same brightness, it will be considered a tie. If there are three bulbs of the same brightness, the one with two of these bulbs wins.
