Build a 2-Stage Power Attenuator for Your High Powered Tube Amp
... The idea is to use a resistor matrix to cut the both voltage and current and in doing so, we cut the power. Remember, power = voltage x current. We select the correct values of resistors so that we can attenuate both current and voltage at the correct proportion — thus keeping the impedance constant ...

A resistor which has a larger physical size has a larger surface area to transfer heat to the surrounding air and therefore can dissipate a larger power without overheating. Most of the resistors used in our lab experiments will be ½ W or ¼ W resistor ...

... So we can use a single resistor to replace the two resistors. The two 10 kΩ resistors have the same pair of nodes, hence they are in parallel. To combine the parallel resistors, we can take the reciprocal of the first resistance and take the reciprocal of the second one and add together, and then ta ...

... Diodes are “one-way” devices that only allow current to flow in one direction. An LED is a diode that emits light when sufficient current is flowing through it. Diodes are used in many, many applications such as: • LED flashlights and light bulbs provide very bright light and use significantly less ...
