Current Voltage Resistance And Ohm S Law Worksheet Answers

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.

Current voltage resistance and ohm s law worksheet answers.

Ohm s law would suggest an infinite current current voltage divided by zero resistance. The current flowing through the resistor is directly proportional to the voltage applied across it. If you think that the wire used in the experiment is not resistance less i e. 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.

Yet the experiment described yields only a modest amount of current. Adjust the voltage and resistance and see the current change according to ohm s law. Resistance and ohm s law worksheet. The connection between current voltage and resistance was discovered in 1827 by georg ohm a german physics and maths teacher.

It is represented by the symbol w. This uneditable pdf file includes 3 pages with answers to each. Get free access see review. The majority of equations and laws for analyzing circuits can be derived directly from ohm s law.

In this physics worksheet students use ohm s law to solve for voltage current and resistance. Show your work and box your answer. About this quiz worksheet. Predict how current will change when voltage of the circuit is fixed and resistance is varied.

Now you should understand the concepts of voltage current resistance and how the three are related. The irresistible georg ohm. They answer 13 problem solving questions using ohm s law. The formula v i r is known as ohm s law.

It was such an important discovery that the unit of resistance is called the ohm. It does have resistance and that this accounts for the disparity between the predicted and measured. Sample learning goals predict how current will change when resistance of the circuit is fixed and voltage is varied. How much current does it draw.

Find the applied voltage of a circuit that draws 0 2 amperes through a 4800 ohm resistance. Find the applied voltage of a telephone circuit that draws 0 017amperes through a resistance of 15 000 ohms.
