Question

The diagram below depicts three different circuits that light a bulb. The batteries are identical 1.5 V cells, and the light bulbs are identical.

1. Has 1 battery, 1 lightbulb in circuit
2. Has 2 battery, 1 lightbulb in circuit
3. Has 3 battery, 1 lightbulb in circuit

Which circuit has the greatest voltage drop across the light bulb?
Which circuit has the greatest current flow?
no idea, Do not see circuit.
a. circuit #3.

b. circuit #3.
I am assuming the 1.5v. batteries are connected in series.
If the 1.5v batteries are connected in parallel, the voltage and current in
all 3 circuits are equal.
