you can usually get them at any supply store like office max.

The amperage rating of the transformer in a 12V power supply cannot be changed. The size of the copper windings determine the power load (amps) it can handle and the point where the lead is tapped off of the windings determine the voltage. The only way to increase the amperage would be to tap closer to the core which would lower the voltage.If you need more amps you have to have a heavier transformer.

The band Air Supply were formed in 1975. They an Australian-British duo, consisting of lead vocalist Russell Hitchcock and guitarist and singer-songwriter Graham Russell.
the blue lead is the display lead (VGA) the power supply and you might have an ethernet cable (grey one, for internet) the ethernet cable is for the internet if you computer isnt wireless or if you want better connection the VGA is to connect to a computer screen or any external display the power lead is for power.
A power lead (is a cable) that connects the mains electrical supply to an electronic device. An example is the cable from a computer to the socket in the wall. Obviously, a washing machine (and most household appliances) need power leads too.
Many situations may lead a user to search for a generic laptop power supply. The original power supply may have become ineffective or may have been lost during travel. Laptop power supplies are the connection between the laptop and a power source. This cable is used to recharge the batteries that are a component of the notebook. Regardless of the reason for replacement, the user must decide whether to buy a name brand power supply or go with a generic manufacturer.
The vehicle battery's main purpose is to supply power for the starting system and to power some accessories when the engine is not running. The proper procedure for changing or installing a battery... remove the battery cable first from the negative battery terminal, then from the positive. Install opposite, attach the positive cable lead, then the negative.
A mains lead is the power cable for the strip heater. The mains lead is single-insulated.
A power cord, line cord, or mains cable is a cable that temporarily connects an appliance to the mains electricity supply via a wall socket or extension cord. The terms are generally used for cables using a power plug to connect to a single-phase alternating current power source at the local line voltage"(generally 100 to 240 volts, depending on the location). The terms power cable, mains lead, flex or kettle lead are also used. A lamp cord is a light weight ungrounded two wire cord used for small loads such as a table or floor lamp. The term cord set is also used to distinguish those cords that include connectors molded to the cord at each end.
Two - the power lead and the data cable that connects to your computer
A USB hard disks that does not require a power supply is powered by your computer via the USB connection. Where as others require an external power supply because of the amount of power they require. It is usually a "wall wart" type that plugs in to your wall socket with a lead that plugs in to the disk drive.
It depends what you mean by 'power lead' If you mean JUST the flex from the mains to the power adapter, cost is around £8.00 - However - if you mean to replace the whole power supply, it could be as much as £30 depending on the make & model.
By definition, the terms 'leading' and 'lagging' refer to what the load current is doing with respect to the supply voltage. So, for a 'lagging power factor', it is the current that is lagging.
The negative battery lead cable is to be connected to the negative lead terminal on the battery.
just lead to a shift in the supply curve.
