How to Find the Power Formula Number 3 for Electrical Circuits, Calculating Power Without Current

In this video we look at how the third power formula for electrical circuits can be found. We do this by combining our basic power formula with Ohm's Law. We then prove that this is the case by looking at a practical experiment using some values from a previous video.

Back to my late Teens ... God bless .

[@JoeRobinsonTraining]

Hope it brought back good memories!

[@tedlahm5740]

Thank you for the follow thru. All three covered.

[@JoeRobinsonTraining]

No worries!

[@markrowland5393]

Nice one, Joe. Well explained and well demonstrated.

[@JoeRobinsonTraining]

Thanks Mark, more to come!

Keeb up the good job joe ..👍

[@JoeRobinsonTraining]

Thanks I will!

With an inductive load do you factor into the formula the power factor?
What value would you use as the pf?

[@ndubi1502]

Great 👌

[@colinleahy4824]

Well done 👍 great to see .

[@JoeRobinsonTraining]

Thanks Colin, stay tuned for more!

[@technicalgyaan]

Well done boss👍

[@JoeRobinsonTraining]

Thank you!

Sir what about P=VICOS@

[@pault4793]

Joe , why have use of the other power formula why not just stick with P=IxR

[@JoeRobinsonTraining]

Hi Paul, great question. You could for example use the formula in this video to figure out how much power a resistor would dissipate in a circuit without calculating the current first. It saves one step in the calculation. Stay tuned for more!

Looks all so familiar to me 👍😂
