why do we use a dual power supply? Why, for instance, do we use +12 and -12 volt instead of just a 12 volt power supply.

Pranav Jha said:In my circuit, i have connected one end of my solenoid to +12 volt and the other end to a ground (where +12 and -12 are connected together). So, how is that any different from connecting it to a 12 V battery?

Zz.
Pranav Jha said:I guess that it is AC that has resulted in the reversing magnetic field. If so, how does Dual power supply provide AC ?
Pranav Jha said:With my AC question what i meant was: "Does the split power supply provide an Alternating current?'

A dual power supply is a type of power supply that provides two separate voltages, typically +12V and -12V, for electronic circuits and devices. It is commonly used in applications where both positive and negative voltage sources are needed.
A dual power supply offers several advantages over a single power supply. It allows for the use of both positive and negative voltages, which is necessary for certain electronic components and circuits. It also provides a more stable and regulated power supply, reducing noise and interference in the circuit.
Devices that require both positive and negative voltages, such as op-amps, audio amplifiers, and analog-to-digital converters, typically require a dual power supply. It is also commonly used in industrial and scientific equipment, as well as in some electronic hobbyist projects.
Building a dual power supply requires some knowledge of electronics and basic circuit design. It involves using a transformer to step down the AC voltage from a wall outlet, followed by rectification and filtering to convert it into DC voltage. The resulting DC voltage is then regulated and split into two separate outputs, +12V and -12V, using voltage regulators.
Yes, it is important to follow proper safety precautions when working with any type of power supply. This includes proper grounding, using appropriate voltage and current ratings, and avoiding contact with exposed wires or components. It is also important to use caution when working with AC voltage and to ensure that the power supply is properly designed and built to avoid any potential hazards.
