| | I have a question on the replacement of the a specific resistor. On the handyboard there is a 3.83K 1/8W resistor. I just received in the mail the last pieces for the board and was shipped a 3.83K 1/4W resistor. Is the wattage citical on this (...) (27 years ago, 10-Apr-97, to lugnet.robotics.handyboard)

| | | | (...) I believe the wattage just tells you how much power the resistor can reasonable dissipate. Therefore using a transistor which can dissipate more power than what the design calls for is alright, but using one that dissipates less power is bad. (...)

| | | | (...) In this case, no problem. The computation of power is simple... Watts = Volts X Amps and ohms law is... Volts = Resistance X Amps Using the traditional I = current (they say it comes from the French word for Intensity) R = Resistance E = (...) (27 years ago, 12-Apr-97, to lugnet.robotics.handyboard)
