Answer 1

As $R_{1}, R_{2}$ and $R_{3}$ are in parallel combination therefore voltage across them will be same that is $V = 6.0 V$ ,
given $R_{2} = 6.0 Ω$
rate at which energy used by $R_{2}$ ,
$P = V^{2} / R_{2} = 6 . 0^{2} / 6.0 = 6.0 W$

Answer 2

As

R_{1}, R_{2}

and

R_{3}

are in parallel combination therefore voltage across them will be same that is

V = 6.0 V

,

given

R_{2} = 6.0 Ω

rate at which energy used by

R_{2}

,

P = V^{2} / R_{2} = 6 . 0^{2} / 6.0 = 6.0 W

If each resistor has a resistance of $6.0 o h m s$ what is the rate at which energy is used by resistor $2$ ?

$1.0 W$

$36.0 W$

$6.0 W$

$24.0 W$

$18.0 W$

As $R_{1}, R_{2}$ and $R_{3}$ are in parallel combination therefore voltage across them will be same that is $V = 6.0 V$ ,
given $R_{2} = 6.0 Ω$
rate at which energy used by $R_{2}$ ,
$P = V^{2} / R_{2} = 6 . 0^{2} / 6.0 = 6.0 W$
