Concept explainers

Temperature Variance of Resistance

Electrical resistance or simply resistance is the property of a material that opposes the free flow of electrons through it. The total amount of resistance to the flow of charges (or current) is affected by many factors like the length of the conducting material, its cross-sectional area, resistivity, and temperature.

Question

The resistance equivalent is 1.43 ohms. Now a 12V battery is connected between points A and B. What is the currrent in the 4 ohms resistor?
