Household power supply is converted from 240 (RMS) mains power to a more practical value of 20 V(RMS), this enables the supply to satisfy the requirements of the home. This adaptation is employed as large voltage equates to large cables and thus higher expenses. Another explanation why mains power is converted, despite neither household nor industries having a single common need for the supply is that society is progressing towards a micro environment. Electricians and engineers communication electric circuit designs through circuit diagrams. This practice is used as this pictorial method of illustrating how the components connect together is a simpler version that is easier to...
