How To Calculate The Power Delivered To A Resistor Using The Current Find the voltage (v) across resistor r 1 of power rating p 1 using the formula: v = √ (p 1 × r 1) calculate the power dissipated by the second resistor (r 2 ), p 2 = v 2 r 2. the overall voltage is 14.14 v, so the resulting power equals 20 w. Use omni's power dissipation calculator to determine the power dissipated in series and parallel resistor circuits. just enter the applied voltage and the resistances of the resistors. the calculator will calculate the equivalent resistance of the circuit, the total current through the circuit, and the power dissipated by the resistors.
How To Calculate The Power Delivered To A Resistor Using Resistance Therefore, to calculate the power dissipated by the resistor, the formulas are as follows: p (power dissipated) = i2 (current) × r (resistance) or. p (power dissipated) = v2 (voltage) ÷ r (resistance) so, using the above circuit diagram as our reference, we can apply these formulas to determine the power dissipated by the resistor. voltage = 9v.
