Oxygen Supply in Submarines Nuclear submarines can stay under water nearly indefinitely because they can produce their own oxygen by electrolysis of water.

How many liters of O2 at 298 K and 1.00 bar are produced in 1.00 hr in an electrolytic cell operating at a current of 0.0200 A?

You will hear a hissing sound because of the carbon dioxide escaping the can or bottle

Sorry i don’t know what to do

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current
