What Effect does battery capacity on a circuits internal resistance?
Batteries are rated as ampere/hour any circuit that draws power from it effects it. The lower the internal resistance of the circuit the shorter the useful battery life as discharged.
Resistivity of copper at 20 degree celsius?
Resistivity allows us to compare different conductors' abilities to transmit electric current that is independent of the physical dimensions of the conductors.Resistivity is defined as 'the resistance of a unit length of a substance with a uniform cross-section'. In SI, the unit of measurement of resistivity is the ohm metre; in US customary units, it is expressed in ohm circular mil per foot.So, to finally answer your question, the resistivity of copper is 17.5x10-9 ohm metres at 20oC. To find the resistance of a copper conductor, you can then use the equation:resistance = resistivity x (area / length)Additional AnswerThe resistivity of copper depends on the temperature it which it is measured. At 25°C, it is about 17 nΩ.m, or 1.7 µΩ.cm.The resistance of a conductor is then p * L / A, where p is the above number.So for a wire with a length of 1 m (i.e. 100 cm), and a cross sectional area of 2 cm², the resistance is 17e-6 * 100 / 2 = 85 µΩ
What is the definition of controled experiment?
the definition for a controlled experiment is it test the effects of one factor
What kind of connecting wire should be used in physics Lab thinner or thicker?
If the electrical characteristics of the wire itself are not part of the experiment, then the wire should be thick and short. This minimizes both the resistance and inductance of the wire, and therefore the chances that the effects of the wire could influence the observations of the experiment.
How do you know that a variable is really a control variable and what is the property of control variables?
If you're performing an experiment in which your result depends on multiple variables, but you're just interested in how one of those variables effects the result, you would generally keep all of the other variables constant in order to negate their effects. Those variables that you're keeping constant are called control variables, and you would choose them based on the experiment. For example, say you wanted to determine how changes in resistance effect a circuit's current. Well, current is dependent on not only resistance, but voltage as well, and since you're only interested in the effects of resistance, you would make voltage the control variable, keeping it constant.
A scientist conducts a experiment to test the effects of the light on earthworm activity What is the variable in this experiment?
temputure
Something the effects the outcome of an experiment is called a?
a variable
What is friction and what effects does it have on motion?
Friction is the sum of resistance to motion and as for resistance, it slow down the motion.
What is the single factor that is changed in an experiment?
the independent variable is the factor of an experiment that is altered in an attempt to understand its effects on the experiment's subject
How many variables are generally tested in an experiment?
The trick to designing a good experiment is to figure out a way for it to test the effects of only one variable, and to avoid any effects of others.
Which of theses factors varies due to effects of the factor being tested in a controlled experiment?
The dependent variable varies due to effects of the factor being tested in a controlled experiment.
