Answer:

formula used,

V=Ir

I=V/r

Explanation:

it is given that,

V=6v

r=2

now,

I=6/2

I=3A

Answer:

18W

Explanation:

Given that,

V=6v\\\\R = 2ohm

And,

Power Dissipated in a circuit

The equation of power is P = V X I

P = I^2 R [ sinceV = IR]

V is the voltage

I is the current

R is the resistance

the formula used for find I,

V = IR\\\\I= V/R

now,

I=6/2\\\\\I=3A

power is

P = VX I\\\\= 6X3\\\\=18 W
