Calculating Power Dissipation in a Resistor
A resistor with resistance \(R = 50\,\Omega\) is connected across a voltage source providing \(V = 10\,\text{V}\). The measured current through the resistor is \(I = 0.20\,\text{A}\).\n\nCalculate the power dissipated in the resistor using the formulas \(P = IV\), \(P = \frac{V^2}{R}\), and \(P = I^2R\). Confirm that all three methods yield the same result. […]
