EC03 - Multimeters and Resistor Rings

Another board where we have to find the resistance value of resistors, but this time we have the aid of a multimeter.

Tutorial (for when you are with the board) 

Tutorial guide for when you have the board with you.

Part 1

All good multi-meters will measure resistance. Normally there will be a number of ranges for different values. Plug the leads into the two red sockets and then move the rotary switch on the multi-meter through the resistance options and workout the value of the hidden resistance. Always start with the highest range (here it's the one marked 2000k - which is 2M) and then move down until you don't get a reading because the value of the resistor is too low. When you think you know the value lift up the flap to see if you are right. Note that meters and resistors are never 100% accurate.

Try finding out the resistance on all the resistors.

Part 2

Resistors have rings so you can work out their value. The card on the board explains how this works. Try and work out the value of the resistors across the top of the board and then use the meter to check your finding.
