Series and Parallel Connections for Batteries
[ad#block] Can you tell me is there an simple way to get 12 volts from 5 volt AA batteries. I know its not exactly a DIY question but if you could help it would be really appreciated.

Thanks Tristan

Thanks for your electrical question Tristan.

Battery Connections and Voltage Output

The Difference Between Series and Parallel Connections

A Series connection or when you place the 5v batteries end to end you increase the voltage by the number of batteries.
For example, if there are 2 5v batteries placed end to end then you would have 10v, 3 batteries would give you 15v.
A Parallel connection is where the batteries are connected side by side, or straight across the terminals, will produce the same voltage but multiply the lifespan of the battery power, where is each battery was 2500mAh it would then be 5000mAh when there is a parallel connection of two batteries.

Example Table of Battery Connections
Each Battery – 1.5v 2500mAh
2 in Series = 3v at 2500mAh (end to end)
2 in Parallel = 1.5v at 5000mAh (side by side)

Electrical Tips

To Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!
The Non-Contact Electrical Tester

This is a testing tool that is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!
The Plug-In Outlet Tester

This is great to troubleshoot a problem with outlet circuit wiring, is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect, Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!
The Wire Stripper and Wire Cutter

A wire stripping tool used to safely strip electrical wires. This handy tool has multiple uses: The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation. The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets.
