How Do You Build A 110 Volt To A Low Voltage Transformer?
It is standard that every house in the US has a wall output of 110 to 120 volts, alternating current. It is also true that just about every device and electronic setup out there will require a completely different voltage. So there is a need to transform the voltage in the wall to that which is needed by the device. Determine your target voltage and current needs. This is important as it will dictate the later steps. for the sake of example, we will be assuming 110 volts in, 11 volts out at 1 ampere of current. Calculate the mains current. A transformer is a device that multiplies and divides. Since we are dividing voltage, the current will be multiplied by an equal ratio. In our example, we are dividing the current by a factor of 10 (110/11 = 10), which means that to arrive at 1 ampere, our mains current is 100 milli-amperes (Mains current x 10 = 1 ampere -> 1/10 amperes = 100 milli-amperes = mains current). Determine wire gauge. You will need two gauges of wire, one for your primary,
