New Understanding Current and Voltage Circuits

Which statement is true if the bulbs have different resistances?

• Current through each bulb is the same and the voltage across them is the same too

• Current through each bulb is the same but the voltage is different across each one

• Current through each bulb is the different and the voltage across each one is different too

• Current through each bulb is different but the voltage across each bulb is the same

The bulbs have difference resistances. What can be said about the current and voltage

• Current is the same in both bulbs, voltage is different across each

• Current is the same in both bulbs, voltage is the same across each.

• Current is different in both bulbs, voltage across each is the same

• Current is different in both bulbs, voltage across each is different too.
