Answer:
144 W
Explanation:
The power absorbed by a resistor is the product of the current passing through it and the voltage drop across it. Hence
[tex]P=IV[/tex]
[tex]P=12\text{ A}\times12\text{ V}=144 \text{ W}[/tex]
Other variations of this formula are derived using Ohm's law, [tex]V=IR[/tex]
[tex]P=I^2R=\dfrac{V^2}{R}[/tex]
[tex]R[/tex] is the resistance of the resistor. It is what causes the voltage drop.
