Question

ale physics valo esko solve kardo! ⬆​

Answer 1

Explanation:

V=4v

R=2ohm

We know that

$\boxed{\sf P=\dfrac{v^2}{r}}$

$\sf \longmapsto \: p = \frac{(4) {}^{2} }{2} \\ \sf \longmapsto \: p = \frac{16}{2} \\ \bf \longmapsto \: p = 8w$

Answer 2

Explanation:

we know that power = v^2/r

so power = 16v/2ohm

=8j
