Resistance = Volts / Amps (R = E / I)
So, R = (200 volts) / (50 microamps)
or 200V / .00005A = 4,000,000 Ohms
(or 4 megaohms)

Ohm's Law:
E = I x R (or Volts = Amps x Ohms)
E = (2 amps) x (50 ohms) = 100 volts

Ohm's Law:
I = E / R (or Amps = Volts / Ohms)
I = (200 amps) / (100 ohms) = 2 amps

Ohm's Law:
R = E / I (or Ohms = Volts / Amps)
R = (90 volts) / (3 amps) = 30 ohms

Ohm's Law:
R = E / I (or Ohms = Volts / Amps)
R = ((110 volts) / (0.125 amps)) - (500 ohms already in the circuit) = 380 ohms
