Many registered nurses (RNs) and licensed practical nurses (LPNs) are finding the education and support they need to reenter nursing by enrolling in a refresher program. Offered through colleges and hospitals, nurse refresher programs are designed for RNs and LPNs who have been out of the field for at least three years. Whether your current nursing license is inactive or lapsed, your state board of nursing requires you to take a nurse refresher course to return to active status.
How to charge a battery. An average car battery has a capacity of around 48 amp hours which means that, fully charged, it delivers 1 amp for 48 hours, 2 amps for 24 hours, 8 amps for 6 hours and so on.
The amp-hour rating of a battery (also known as âAHâ) is a measure of how many amps a battery can supply for a period of time. It is calculated using the formula Amps X Hours. For instance, in the ideal world, this rating would mean that if you have a 33AH 12 Volt battery, you should be able to supply 33 Amps (~412 Watts) out of it for 1 hour, or 16.5 Amps (~206 Watts) for 2 hours, or 8.25 Amps (~100 Watts) for 4 hours, etc.
