Brut [27]

The power delivered to the toaster when it is at its operating temperature is 183.6 Watts

<h3>What is power?</h3>

Power can be described as the ability to do work, however, it can be found through the resistance and the current by using the formular, P=VI.

Voltage V1= 120V

initial current  I=  1.80 A

The power can be calculated using the formula as :

P=VI

where

I= current is 1.53

Voltage V1= 120V

Power= (120 * 1.53)

= 183.6 Watts

Therefore, power delivered to the toaster when it is at its operating temperature is 183.6 Watts

Pilots often take advantage of the ____,which are highly-speed winds between 7km and 16 km above earths surface.
lukranit [14]

They named those winds after the fastest planes they came up against: fighters equipped with jet engines! Jet stream winds in winter time can reach up to 300 MPH as well!
