V^2/R.t or I^2Rt ?
Asked by patric_9432 | 2nd Feb, 2010, 07:30: PM
H = I2 Rt = Pt
where t is the time in seconds. In other words, a resistor heats up more when there is a high current running through a strong resistor over a long stretch of time.
Substituting V/R in I, we get the other equation. Both equations are one and the same.
Hope this helps.
