What is the independent and depentendt variable of "A student lab group performed an experiment with different batteries to determine the effect of the voltage of a battery upon the current in a simple electrical circuit. They put a 1-Volt battery and measured the current in the circuit to be 0.25Amps. They replaced the 1-Volt battery with a 2-Volt battery and measured the current to be 0.56Amps. They continued increasing the voltage and measuring the current. 3-Volts resulted in a current of 0.74Amps. 4 Volts resulted in a current of 1.02Amps. At 5 Volts, they measured a current of 1.26 Amps."

Independent variable is the voltage and the dependent variable is the current

Explanation:

When studying the effect of one variable over another the variable that changes with respect to the other variable is the dependent variable. The variable that does not depend on the other variable is the independent variable.

Generally while plotting a graph the independent variable is the x axis while the y axis is the dependent variable.

Here, the batteries are changed according to their voltages while the current produced is measured.

So, the independent variable is the voltage and the dependent variable is the current.

i think the answer is a, hope this : )
