Question

Is there any limitations to use the formula H=I^2Rt in only series or parallel, or can we use it in both? The same I ask about H=V^2t/R as well. Is there any specifications that one of these may be used only for parallel and not series and vice versa? Give reason also.

Answer 1

Answer:

you have three equations for heat ..

H = I^2Rt = V^2t/R = VIt

So, when the Power of a device depends upon the Current passing through it, then you will use the first formula where

H ∝ I²

When the Power depends on Voltage, then use the second formula where H∝ V²..

-->>The first equation is used when device is connected in series.

--->>The second is used when device is connected in Parallel.

--->> The third is used in a simple circuit.
