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?

What's with these goofy questions?  There's no practical electronics that's doing anything with a minuscule current of .16 microamps through a dead short of 3.4 milliohms.

Anyway,

V = IR = .16 × 10⁻⁶ × 3.4 × 10⁻³ = 5.4 × 10⁻¹⁰

 5.4 × 10⁻¹⁰ volts

Finally a use for dead batteries.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
