Avery is experimenting with a simple circuit. She measures the current in the circuit three different times with a different battery each time. First, she uses a 1.5-volt battery. Next, she uses a 3-volt battery. Last, she uses a 9-volt battery. The resistance stays the same during each test.

Question

How does the current change for each test?

a
The current increases.
b
The current stops.
c
The current remains the same.
d
The current decreases.

Answer 1

a - The current increases.
