Web9 de feb. de 2024 · The first formula is: P = I x V where P is the power, I is the current through the resistor, and V is the voltage drop across the resistor. Power is measured in units of watts (W), which correspond to amperes x volts. Thus, a current of one ampere flowing through a resistor across a voltage drop of one volt produces one watt of heat. WebUsing the variable H to represent heat current, this gives you the equation: H = dQ / dt If you've taken pre-calculus or calculus , you might realize that a rate of change like this is …
