SY R V In the above figure the light bulb at R2 goes out, what happens to the rest of the light bulbs? ) All the light bulbs go out Nothing happens The light bulbs get brighter The light bulbs get dimmer

Please Asap

Two students plan an experiment that connects a bulb to an adjustable voltage source along with a voltmeter and an ammeter to measure voltage and current. They then repeat the experiment with a different sized light bulb. They recorded their data and graphed it on the axes shown below. Light bulb #1 Light bulb 82 Voltage According to the results of their investigation, which bulb had a greater electrical resistance ? O A. Light bulb #2 because it has less current at the same voltage. O B. Light bulb #2 because it had a higher voltage. C. Light bulb #1 because it reaches a higher current. O D. Light bulb #1 because It has more current at the same voltage.

Which statements about electric potential are true? (Select all that apply) A. the value of electric potential will be the same everywhere on a wire B. the value of electric potential at a given point in a circuit depends on the reference point (where V = 0) C. a larger resistor will, for the same current, have a larger voltage drop across it than a smaller resistor D. the value of voltage across a given circuit element is independent on reference point (where V = 0)
