Question

What is the independent variable and dependent varaible 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."

Answer 1

The correct answer is -

The independent variable: different batteries of different voltage.

The dependent variable: measurement of the current in an electrical circuit.

Step-by-step explanation:

the Independent variable in any scientific experiment is a variable that is changed to see the effect on the desired result or cause a difference in the dependent variable. Whereas the dependent variable that is affected by the manipulation or change made in the independent variable, by measure it to see the effect of the changes made in the independent variable or factor.

In this experiment, the voltage of the batteries is changed to see the effect on the change in the current in a circuit thus the independent variable is different batteries of different voltage and the dependent variable is the measurement of the current in an electrical circuit.
