Current voltage resistance and ohm s law worksheet answers.

The connection between current voltage and resistance was discovered in 1827 by georg ohm a german physics and maths teacher. Adjust the voltage and resistance and see the current change according to ohm s law. Predict how current will change when voltage of the circuit is fixed and resistance is varied. This uneditable pdf file includes 3 pages with answers to each.

It is represented by the symbol w. It does have resistance and that this accounts for the disparity between the predicted and measured. If you think that the wire used in the experiment is not resistance less i e. The formula v i r is known as ohm s law.

The current flowing through the resistor is directly proportional to the voltage applied across it. Given the resistance and voltage supplied to a circuit students use ohm s law and circuit rules to find the voltage drop across and current through every resistor. In this physics worksheet students use ohm s law to solve for voltage current and resistance. Find the applied voltage of a telephone circuit that draws 0 017amperes through a resistance of 15 000 ohms.

It was such an important discovery that the unit of resistance is called the ohm. Now you should understand the concepts of voltage current resistance and how the three are related. About this quiz worksheet. Ohm s law is an important concept in the study of electricity and this quiz worksheet will help you test your understanding of its components.

A 20 volt relay has a coil resistance of 200 ohms. Sample learning goals predict how current will change when resistance of the circuit is fixed and voltage is varied. The irresistible georg ohm. The majority of equations and laws for analyzing circuits can be derived directly from ohm s law.

By knowing this simple law you understand the concept that is the basis for the analysis of any electrical circuit. Resistance and ohm s law worksheet. They answer 13 problem solving questions using ohm s law. Yet the experiment described yields only a modest amount of current.

He finally published the law in 1827 and generalized his observations in single statement. How much current does it draw.
