1.

Heat is generated in accordance with the equation H = I2Rt. In that case1. What are the methods to reduce the heat generated?2. If current (I) is reduced to half, how much will be the reduction in heat? (half, one fourth)3. If current (I) is reduced to 1/10 time show much will be the reduction in heat?4. How can we reduce the current without change in power? Find out on the basis of the equation P = V x I.
