The electrical voltage v varies jointly as the current i and the resistance r. substitute a by V, and b by I and c by R.
The electrical voltage v varies jointly as the current i and the resistance r. <br />10. Jan 16, 2021 · V stands for the electrical voltage, k stands for the constant of variation, I for the current and R for the resistance. a=kbc ️ V=kIR. Ohm's law statistics that the voltage (V) across a resistor is proportional to the current (I) and the resistance (R) across it, which translates to V=IR in scientific notation. Therefore, the correct equation representing the joint variation of voltage with current and resistance is option (a) V = kIR . They are related to each other through Ohm’s law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them. Mathematically, Ohm’s law can be . 3 Convert the proportionality to an equality by introducing a constant of proportionality k , resulting in V = kIR . AnswerStep 5: Understand the limitations It's important to note that the equation V = kIR assumes a linear relationship between the voltage, current, and Jul 4, 2025 · What causes a voltage to increase linearly with regards to the current? This linear relationship occurs when we have a constant resistance, following Ohm’s law: V = I R V = I R – as current increases, voltage increases proportionally because the resistance remains the same, creating that beautiful straight-line graph we see in ohmic 10 The electrical voltage V varies jointly as the current I and the resistance R B Solve for the value of the constant of variation k then find the missing value 1 z varies jointly as x and y and z 60 Jan 14, 2024 · Voltage (V), current (I), and resistance (R) are three fundamental quantities in electrical circuits. substitute a by V, and b by I and c by R. The variable y is inversely related to the variable x, thus when x is doubled, y decreases by half of its original value. <br />9. y = kx, with k being the constant and its given value For example, if you know the current I and resistance R, and want to find the voltage V, you can rearrange the equation as V = kIR and substitute the known values to calculate the voltage. Explanation <p> <br />8. The statement given involves joint variation, therefore the mathematical equation must follow the joint variation formula a=kbc. kanl ankow kzjvlg qzqsd pfal vqoah leipv ptagxh exyflf wtuxoq
