SUMMARY

This discussion centers on the relationship between voltage, current, and resistance as defined by Ohm's Law. According to the law, if voltage remains constant and current increases, resistance must decrease. The formula Voltage = Current × Resistance is pivotal in understanding this relationship. Participants emphasized the importance of solving for resistance (R) and utilizing arrow analysis to visualize changes in resistance.

PREREQUISITES
  • Understanding of Ohm's Law
  • Basic knowledge of electrical circuits
  • Familiarity with the concepts of voltage, current, and resistance
  • Ability to perform algebraic manipulations
NEXT STEPS
  • Study the implications of Ohm's Law in practical circuits
  • Explore the concept of arrow analysis in electrical engineering
  • Learn about the effects of varying resistance on circuit performance
  • Investigate real-world applications of voltage, current, and resistance relationships
USEFUL FOR

This discussion is beneficial for high school students studying physics, particularly those focusing on electrical concepts, as well as educators seeking to clarify these fundamental principles.

If Voltage is constant and Current (amps) increases then Resistor should be?
increased, decreased or the same...

i do not understand this at all..i don't understand the relationshop between them...could someone please help me? I am in my 4th yr at high school so please...no hard words!

look up Ohm's law. That is the relationship between voltage, current and resistance. Solve for R and use arrow analysis to see how resistance should change.

Resistance should be decreased. Voltage = Current*Resistance (Ohms Law)
