What Is Ohm's Law?
Definition and Basic Concept
Ohm's Law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature and material remain constant. Mathematically, it is expressed as:
- V = IR
Where:
- V = Voltage (volts, V)
- I = Current (amperes, A)
- R = Resistance (ohms, Ω)
- Develop problem-solving skills
- Understand the relationship between voltage, current, and resistance
- Apply mathematical formulas to real-world scenarios
- Prepare for exams and practical applications
- Multiple-choice questions
- Fill-in-the-blank problems
- Calculation exercises
- Scenario-based problems
- Answer keys for self-assessment
- Identify the known variables: Determine which of voltage, current, and resistance are provided.
- Choose the appropriate formula: Depending on the unknown variable, select V = IR, I = V/R, or R = V/I.
- Substitute known values: Plug the known values into the formula.
- Calculate the unknown: Perform the mathematical operations carefully.
- Verify units and reasonableness: Ensure the answer makes sense within the context of the problem.
- Voltage: V = IR
- Current: I = V/R
- Resistance: R = V/I
- Use V = IR
- V = 2 A × 50 Ω = 100 V
- Use I = V/R
- I = 20 V / 100 Ω = 0.2 A
- Use R = V/I
- R = 120 V / 3 A = 40 Ω
