A resistance spot-welding operation is performed on two pieces of 1.5-mm-thick sheet steel using a current of 12,000 A for a duration of 0.20 seconds. The contacting electrodes are 6 mm in diameter. If the effective resistance of the joint is assumed to be 0.0001 ohm, calculate the total heat generated in the process.
