Ohm s law would suggest an infinite current current voltage divided by zero resistance. This uneditable pdf file includes 3 pages with answers to each. A 20 volt relay has a coil resistance of 200 ohms. About this quiz worksheet.

He finally published the law in 1827 and generalized his observations in single statement. Find the applied voltage of a telephone circuit that draws 0 017amperes through a resistance of 15 000 ohms. The formula v i r is known as ohm s law. Yet the experiment described yields only a modest amount of current.

Get free access see review. The irresistible georg ohm. Sample learning goals predict how current will change when resistance of the circuit is fixed and voltage is varied. It was such an important discovery that the unit of resistance is called the ohm.

In this physics worksheet students use ohm s law to solve for voltage current and resistance. Find the applied voltage of a circuit that draws 0 2 amperes through a 4800 ohm resistance. Resistance and ohm s law worksheet. The majority of equations and laws for analyzing circuits can be derived directly from ohm s law.

It is represented by the symbol w. The connection between current voltage and resistance was discovered in 1827 by georg ohm a german physics and maths teacher. If you think that the wire used in the experiment is not resistance less i e. Now you should understand the concepts of voltage current resistance and how the three are related.

By knowing this simple law you understand the concept that is the basis for the analysis of any electrical circuit. 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. The current flowing through the resistor is directly proportional to the voltage applied across it. Predict how current will change when voltage of the circuit is fixed and resistance is varied.

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. Adjust the voltage and resistance and see the current change according to ohm s law.
