Voltage, otherwise known as electrical potential difference (denoted ∆V and measured in volts) is the difference in electric potential between two points (adapted from Wikipedia). Voltage can be constant (DC) or varying (AC).

Vin connects to the battery. The upper connection goes to + and the lower one to -. Vout is the output: it goes to whatever you're trying to supply power for. The upper connection is + and the lower o …

As Spehro said, "The 741 is not a single-supply op-amp." That means that the circuit must use a split supply, not a single supply. +V and -V are relative to ground. You need two power sources. For +V …

Power supplies don't push current; loads pull. 6A is the maximum current that the supply can provide, but it's perfectly happy to supply less. If you have a load that's rated for 12 volts and you atta …

For most uses of a bench power supply you're interested in providing a steady voltage. That's what the voltage setting is for. The current setting is a current limiter -- if your load draws more … current than you've set the limiter for, it lowers the voltage until the load draws only the amount that you set the limiter for. The idea is to keep your electronics from frying if you've made a mistake. …
