Resistance Welding Solution

STEP 0: Pre-Calculation Summary

Formula Used

Resistance Welding = Current Magnitude^2*Resistance*Time
E = I^2*R*t_sec
This formula uses 4 Variables

Variables Used

Resistance Welding - (Measured in Joule) - Resistance Welding is characterized with a high current passing through the materials to be welded between the electrodes under pressure for generating concentrated heat to form a weld.
Current Magnitude - (Measured in Ampere) - The Current Magnitude is the magnitude of the rate of flow of charged particles.
Resistance - (Measured in Ohm) - Resistance is a measure of the opposition to current flow in an electrical circuit. Its S.I unit is ohm.
Time - (Measured in Second) - time is what a clock reads, it is a scalar quantity.

STEP 1: Convert Input(s) to Base Unit

Current Magnitude: 988.6 Ampere --> 988.6 Ampere No Conversion Required
Resistance: 10.1 Ohm --> 10.1 Ohm No Conversion Required
Time: 30 Second --> 30 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

E = I^2*R*t_sec --> 988.6^2*10.1*30

Evaluating ... ...

E = 296130977.88

STEP 3: Convert Result to Output's Unit

296130977.88 Joule -->296130.97788 Kilojoule (Check conversion here)
