What is the difference between volts amps and watts

Now that you have a basic understanding of the fundamentals of power and electricity, you should be able to tackle your RV electrical projects with a little more confidence. Our Reno, Nevada-based sales and customer service team is standing by at to take your questions! Also join us on Facebook , Instagram , and YouTube to learn more about how lithium battery systems can power your lifestyle, see how others have built their systems, and gain the confidence to get out there and stay out there.

Hi Suzanne, happy to help with this one! Our team suggests using just an adapter to a V device will be enough for your rig! Please let us know if you have any additional questions and have a great rest of your afternoon. I want to build a camper can I the spring. I want a BattleBorn lithium battery for my electric needs. Will I need an inverter, converter, or router or all 3? How much solar will I need?

Hi Carol, thank you for reaching out. Our team is able to provide a thorough assessment of your system and what it will need. Please give them a call at and they will be more than happy to help!

The resistance in electrical wires consumes power, and the power consumed increases as the current going through the wires increases.

You can see how this happens by doing a little rearranging of the two equations. What you need is an equation for power in terms of resistance and current. Let's rearrange the first equation:. What this equation tells you is that the power consumed by the wires increases if the resistance of the wires increases for instance, if the wires get smaller or are made of a less conductive material.

But it increases dramatically if the current going through the wires increases. So, using a higher voltage to reduce the current can make electrical systems more efficient. The efficiency of electric motors also improves at higher voltages.

This improvement in efficiency is what drove the automobile industry to consider switching from volt electrical systems to volt systems in the s. As more cars shipped with electric-powered amenities — video displays, seat heaters, "smart" climate control — they required thick bundles of wiring to supply enough current.

Switching to a higher-voltage system would provide more power with thinner-gauge wiring. The switch never happened , because carmakers were able to boost efficiencies with digital technology and more efficient electric pumps at 12 volts.

But some new models employ hybrid systems with a separate volt generator to power advanced features like idle shut-off while increasing overall system efficiency. Sign up for our Newsletter! Mobile Newsletter banner close. Mobile Newsletter chat close.
