# Power And Energy Through Resistor#

A 9 $$\textrm{ V}$$ battery is used to supply current to a {{params.R} $$\rm\ k\Omega$$ resistor. Assume the voltage drop across any wires used for connections is negligible.

## Part 1#

What is the current through the resistor?

## Part 2#

What is the power dissipated by the resistor?

## Part 3#

What is the power input from the battery, assuming all the electrical power is dissipated by the resistor?

## Part 4#

What happens to the energy dissipated by the resistor?
