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

Answer: 5.4 * 10⁻¹⁰ volts

Finally a use for dead batteries.
