I've never owned or used a breadboard before, but considering purchasing one in my current price range. My questions are,
1. Apparently some are not "powered" ? I assume you have to add batteries or generators, rheostat ?
2. I'm looking at this (apparently older) one, -Elenco 9440 Breadboard With JW-350 Jumper Wire Set, Model 9480WK, but it says nothing about whether,
a. it has a power source
OR
b. what the voltage range is
OR
c. if it has an adjustable voltage source.
Appreciate any input.
