Your teacher decides to replace a 60-W incandescent lightbulb in her kitchen with a 9-W LED bulb. 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.

A circuit you’re building needs a voltmeter that goes from 0 V to a full-scale reading of 5.0 V. Unfortunately, the only meter in the storeroom is an ammeter that goes from 0 μA to a full-scale reading of 500 μA. It is possible to use this meter to measure voltages by putting it in a measuring circuit as shown. What value of R must you use so that the meter will go to full scale when the potential difference ΔV is 5.0 V? Assume that the ammeter is ideal.
