Problem 47PE

Show that the units 1 A2 ⋅ Ω = 1 W , as implied by the equation P = I2R .

Step-by-Step Solution:
Step 1 of 3

Solution 47PE

[P] = [I2] [R]

Substitute (ohm) for [R] and A (Ampere) for [I],

[P] = A2. Now by ohm’s law,

V= IR

Unit of R is,

[R] = Substitute A (Ampere) for [I] and V (Volt) for[V] . Rewrite the unit of power as,

[P] = A2. Substitute for .

[P] = A2. ...
