WebMay 8, 2024 · V 2 = V 1 − I R 1. where I R 1 is the voltage drop over R 1. You can iterate this until you reach V 4. If every resistance is the same every voltage drop is also the same and the voltage is equally divided over the resistors. Note that you can add a constant to all the voltages without changing the setup. WebAug 18, 2012 · Put the two 12V fans in series. Now your load is 24V @ 20mA. The effective resistance is 24V/0.02A = 1200Ω. Now you need to burn off 48V - 24V @ 0.02A, i.e. the same amount as the load. Hence you need a 1200Ω resistor in series. Calculate the wattage = 24V x 0.02A = 0.48W. Use a 1200Ω resistor, 1W or higher. B. french bulldog season cycle https://bassfamilyfarms.com
