Equivalent Resistance in series circuit

[matt72lsu]

Homework Statement

Three resistors with values of 7.0 Omega, 12 Omega, and 16 Omega are connected in series in a circuit with a 9.0 V battery.
a) What is the total equivalent resistance?
b) What is the current in each resistor?
c) At what rate is energy delivered to the 16 Omega resistor?

Homework Equations

I= V/Rs
P = V^2 /R ?

The Attempt at a Solution

I got "a" but missed "b". i used the first equation and got .26 then divided that by 3 but I guess that's not what you do. For "c" i really have no clue. help!

In series connection the current is the same in all the resistances.
For "c", the power can also be written as P = I^2*R.

 

[matt72lsu]

so for b the answer would be just .26 and not divide by 3?

 

[rl.bhat]

Yes.
