Voltage.
Independent Variable: Time (how long each battery operates in a given device) Dependent Variable: Voltage.
Is Size of battery A independent variable?
The dependent variable is the number of batteries. The dependent variable is the electromagnet. The independent variable is the number of batteries.
What is the dependent variable in the lemon battery experiment?
The independent variable is the amount of lemons. The dependent variable is the voltage measured.
What is the dependent variable in this experiment?
The dependent variable is the variable that is being measured or tested in an experiment. 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores, since that is what is being measured.
What is the dependent variable in a potato battery experiment?
Dependent variable is the electrical power. (Measured as voltage, in a closed circuit, while you have a low current lamp in the circuit.) Constants are the size of electrodes and the area in contact with potato (or potato juice). Control variable is the temperature (Air temperature as well as the potato temperature).
What are some examples of independent and dependent variables?
Independent variable causes an effect on the dependent variable. Example: How long you sleep (independent variable) affects your test score (dependent variable). This makes sense, but: Example: Your test score affects how long you sleep.
Which brand of battery lasts the longest independent variable?
The Duracell battery lasts the longest, closely followed by Energizer and then Eveready. In general, the alkaline batteries are found to perform better than their non-alkaline counterparts.
What is the independent variable in a battery?
Independent Variable: Time (how long each battery operates in a given device) Dependent Variable: Voltage.
What is the independent variable on a fruit battery?
For example, if you are testing different kinds of fruit (e.g., oranges vs. lemons), then your independent variable would be the type of fruit. The dependent variable is what changes in response to variations in the independent variable. In fruit battery experiments, the dependent variable is usually a voltage.
What are control variables?
A control variable is an element that is not changed throughout an experiment, because its unchanging state allows the relationship between the other variables being tested to be better understood.
What are some examples of dependent variables?
It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.
What is my independent and dependent variable?
The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.
What is the independent variable in an experiment example?
The independent variable (IV) is the characteristic of a psychology experiment that is manipulated or changed by researchers, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.
What is the controlled variable in a circuit?
Control Variables are the material, the cross section area and the temperature of the wire. These are kept the same by not changing the wire during the experiment, by keeping the current small and opening the switching between readings.
What is the controlled variable in a series circuit?
Control Variables are the material, length, cross section area and temperature of the wire.
What is the independent dependent and controlled variable in science?
Identify the variables
Independent variable – the variable that is altered during a scientific experiment. Dependent variable – the variable being tested or measured during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment.
What is the dependent variable meaning?
Definitions. Dependent Variable. The variable that depends on other factors that are measured. These variables are expected to change as a result of an experimental manipulation of the independent variable or variables.
Is time a dependent variable?
Time is usually viewed as the independent variable for the simple reason that it doesn’t depend on anything else. Time simply ticks by at the same rate wherever you are (in non-relativistic context), independent of other variables so it doesn’t make sense to express time as a dependent variable.
How do you know if a variable is independent?
You can tell if two random variables are independent by looking at their individual probabilities. If those probabilities don’t change when the events meet, then those variables are independent. Another way of saying this is that if the two variables are correlated, then they are not independent.

Are zinc batteries better than alkaline?
As expected, the capacity of both batteries is different. Because of the composition, an alkaline battery delivers more energy than a zinc battery. The only consequence of this is that both batteries should be used in different applications.
