If light bulb A burns out, what will happen?

• light bulb B will still work but C will not

• none of the light bulbs will work

• light bulb C will still work but B will not

• light bulbs B and C will continue to work

• none of the lights will work

• light bulbs B and C will continue to work

• light bulb B will work, but C will not

• light bulb C will work, but B will not

If the Voltage is increased and the resistance stays the same, Current will

• Increase
• Decrease
• Stay the same
