Stu Wanted To Calculate The Resistance Of A Light Bulb Connected To A 4.0-V Battery, With A Resulting Current Of 0.5 A. He Used The Formula R = Vi And Obtained An Answer Of 2 . Was Stu’s Answer Correct? How Do You Know?. Making use of ohm's law, the resistance of the light bulb is 8 ohms and stu’s solution changed into wrong. A document with notes and questions on ohm's law, electric current, and resistance.
SOLVED Stu wanted to calculate the resistance of a light bulb from www.numerade.com
See the explanation, formula, and examples from verified experts and. He used the formula r=ui and obtained an answer of 2 ω. Includes an example of a wrong calculation by stu and the correct formula to use.
Given That The Current (I) Is 0.5A And The Voltage (V) Is 4.0V.
Present day = zero.5 amperes. R = 4.0v / 0.5a = 8 ohms. To calculate the resistance of the light bulb, we would apply ohm's law:
In Other Words, The Relationship Between Voltage And Current Is Constant:
He used the formula r = vi and obtained an answer of 2. Ohm's law states that at constant temperature, the current flowing through an electrical circuit is directly. Plugging these values into the formula, we get r = 4.0 v / 0.5 a = 8 ohms.
Substitute The Values Into The Formula R=V/I To Find The Resistance.
