What is Attenuation? In simple terms, Attenuation is the loss of an electrical parameter of a signal (or an electromagnetic wave) such as voltage, current or power during its transmission. The amount of attenuation is usually the ratio of the electrical parameter at the output to the same parameter at input under specific conditions. As the signal travels along the cable (or a transmission line), it gradually gets weakened due to attenuation....

Generally, electrical and electronic appliances that we use in our home are controlled with the help of switches i.e. we toggle the switches to turn the appliance ON or OFF.
