5. [8 Points] The battery in the in the circuit below provides 9 V of potential to the circuit.
Originally there is a 4.5 resistor installed in the circuit, and there is a 2.0 amp current
running through the circuit.

(a) What is the power emitted by the resistor?
(b) If the resistance is doubled, what is the new current?
(c) if the resistance is doubled, what is the new power emitted by the resistor?
