Ronny has a device of resistance 220 ohm. when the device is on, it draws a current of 0.5 ampere. how much power does the device consume? the device consumes a power of blank

The device consumes a power of 55 watts.

Step-by-step explanation:

According to the Joule's Law,   , where Power in watts, Current in amperes and Resistance in ohms.

Given that, the device has resistance of 220 ohms and it draws a current of 0.5 ampere. That means,   ohms and ampere.

Plugging these values into the above formula, we will get.........

So, the device consumes a power of 55 watts.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
