Answer:
Current
Step-by-step explanation:
The equation you mentioned is also known as Ohm's law, which can be applied for any circuit containing a battery and one (or more) resistors:
where
V is the voltage
I is the current
R is the resistance
We can re-arrange the equation and rewrite it explicitely for I, the current, to match the equation mentioned in the text of the question, and we have:
