Voltage Drops

How does the voltage drop across globe 1 compare with the voltage drop across globe 2 & 3 in a parallel circuit?

• The voltage drop across lamp 1 is greater

• The voltage drop across lamp 1 is less

• The voltage drops are equal across all 3 lamps

• It depends on which lamp was connected first
