Ohm s law example questions. He finally published the law in 1827 and generalized his observations in single statement. But this time we don t know the voltage of the battery. Temperature strain etc do not change. Ohm s law states that the voltage across a conductor is directly proportional to the current flowing through it provided all physical conditions and temperature remain constant.

This relationship is called ohm s law and be stated as. Let us try another example. Ohm s law webquest print page. Hence in the graph of v against i given above the slope of the graph is the resistance.

Below we have a circuit with a resistor and a battery again. You can change your answer if you want. Use ohms law to relate resistance current and voltage. To take the quiz click on the answer.

In national 5 physics calculate the resistance for combinations of resistors in series and parallel. Ohm s law practice problems. The current flowing through the resistor is directly proportional to the voltage applied across it. The circle next to the answer will turn yellow.

All the questions on this quiz are based on information that can be found at physics. If you don t like calculating things yourself check out this calculator for ohm s law. Solution to example 5 ohm s law v r i is similar to equation of lines of the form y m x and we know that m is the slope of the line y m x. Take a 5 question quiz.

Ohms law quiz practice test questions 1. If i is the current flowing through the conductor when a potential difference v is applied then according to ohm s law the relation between the applied potential difference v and flowing current i is give by. Required fields are marked name email website. For webquest or practice print a copy of this quiz at the physics.

The current i flowing through a conductor is directly proportional to the potential difference i e.
