3. As part of an engineering team at Space-X designing microcircuitry to control rocket launch angle, you must assess the power budget needed to operate 4 fin-control systems. Each system requires 0.16 micro Amperes for circuits with 3.4 milli-Ohms of resistance. How much total voltage is needed to supply these circuits?
