The voltage is unchanged in the circuit. Which of the following statements correctly describes the results of her decision? (Remember V=IR and P=IV) The lower power rating results in a decrease in the current and an increase in the resistance. The lower power rating results in a rise in the current and a rise in the resistance. The lower power rating results in a rise in the current and a decrease in the resistance. The lower power rating results in a decrease in the current and a decrease in the resistance.
