How can a battery have amps but no volts?

How can a battery have amps but no volts?

A battery can have zero volts across it and current flowing if it is being short circuited.

How many amps did Apollo 13 have?

The 2,181 ampere hours in the LM batteries were thought to be enough, but only if the crew turned off every electrical power device that was not absolutely necessary. This included some of the environmental systems, which created frigid conditions inside the spacecraft .

Why did the command module have to be powered down in Apollo 13?

The Service Module is severely damaged and the Command Module has been powered down to preserve its scarce consumables for re-entry. When one of the Service Module’s oxygen tanks exploded, Apollo 13 was on a hybrid free-return trajectory, one that would require significant rocket thrust to get back on a path to Earth.

Does the AMP matter on a battery?

In general, the higher the mAh, the longer the battery will last. If your battery is rechargeable then the mAh rating is how long the battery will last per charge.

Can a battery read 12v and still be bad?

If the battery cannot reach higher than 10.5 volts when being charged, then the battery has a dead cell. If the battery is fully charged (according to the battery charger) but the voltage is 12.5 or less, the battery is sulfated. If your battery cannot even reach a full charge, consider it bad.

How cold did it get inside Apollo 13?

During the Apollo 13 mission, the LM environmental control system provided a habitable environment for about 83 hours (57:45 to 141:05 GET). Cabin temperature remained low due to low electrical power levels. This caused crew discomfort during much of this period, with cabin temperatures ranging between 49°F and 55 °F.

Where is Apollo 13 service module now?

The Apollo 13 Command Module “Odyssey” is now at the Kansas Cosmosphere and Space Center, Hutchinson, Kansas. It was originally on display at the Musee de l’Air, Paris, France.

Why did Apollo 13 have 3 extra batteries?

There were 3 extra batteries in the Command Module to provide power for reentry, but after the explosion, they had been tapped for a short time to provide power when the fuel cells in the CM shut down. Two of three batteries were near full 40-amp-hour strength, but the third only had about half that amount.

Where was Apollo 13 supposed to land on the Moon?

Apollo 13 was supposed to land in the Fra Mauro area. An explosion on board forced Apollo 13 to circle the moon without landing. The Fra Mauro site was reassigned to Apollo 14. At 5 1/2 minutes after liftoff, John Swigert, Fred Haise and James Lovell felt a little vibration. Then the center engine of the S-II stage shut down two minutes early.

How many ampere hours did Apollo 13 have?

The 2,181 ampere hours in the LM batteries were thought to be enough, but only if the crew turned off every electrical power device that was not absolutely necessary. This included some of the environmental systems, which created frigid conditions inside the spacecraft . It is estimated it dipped to 38 degrees F.

How did the Apollo 14 engine shut down?

The Fra Mauro site was reassigned to Apollo 14. At 5 1/2 minutes after liftoff, John Swigert, Fred Haise and James Lovell felt a little vibration. Then the center engine of the S-II stage shut down two minutes early.
