Question

what will be the resistance of a resistor with a dissipated power and current flowing through the resistor 12W and 2A respectively​

Answer 1

Answer:

Here,

• P (power) → 12 w
• I (current ) → 2A

To find :—

• R (Resistance)

We know that ,

$\color{red} \bold { P = I²R}$

$\color{blue} \bold{ \implies \: 12= 2² \: \times R}$

$\color{blue} \bold{ \implies \: 12= 4\: \times R}$

$\color{blue} \bold{ \implies \: R = \frac{12}{4} }$

$\color{orange} \bold{ \implies \: \large\boxed{\bold{R = 3 \: \: Ω }}}$

$\Large{\colorbox{yellow}{\underline{\underline{♠Answer♠:—\:\: 3\:\:Ω} }}}$
