E-Textiles & Ohms Law

I’ve signed up for quite a lot of Future materials workshops this semester, the first two where called E-Textiles and the second was learning about ohms law highlighting that I remembered nothing about physics from school!
E-Textiles explored making simple circuits using a metallic conducting yarn, coin batteries and LEDs. Stitching into fabric to make the circuit and then creating a pocket to hold the battery and ensure that the battery was touching the correct places in the circuit so we didn’t make any short circuits!

9 Volt Battery and LEDs
Ohms Law. We looked at definitions and water flow examples of how electricity well works in a circuit.
Measuring the amount of volts taken by one LED allowed us to calculate how many LEDs we could integrate into a circuit without the bulbs blowing.
If we only wanted one bulb then we had to calculate the correct resistor to use and add that into the circuit.
