But, there is an incremental growth of electronic industries in the country, which has created further scope for new industries in the field of wirewound resistors.

The power dissipated by a resistor may be calculated from its resistance, and the voltage or current involved. The formula is a combination of Ohm's law and Joule's law: where P is the power, R is the resistance, V is the voltage across the resistor, and I is the current through the resistor. A linear resistor has a constant resistance value over all applied voltages or currents; many pract… WebEnergy in Resistors. If a certain amount of power is dissipated for a given time, then ENERGY is dissipated. Energy (power x time) is measured in Joules and by including time (t) in the power formulae, the energy dissipated by a component or circuit can be calculated. Energy dissipated = Pt or VIt or V2t/R or even I2Rt Joules.

WebIn calculating the power in the circuit of Figure 19.21, we used the resistance and Ohm’s law to find the current. Ohm’s law gives the current: I = V / R, which we can insert into the equation for electric power to obtain. P = I V = ( V R) V = V 2 R. This gives the power in terms of only the voltage and the resistance. WebM&I Materials History Brochure. Metrosil products are manufactured by M&I Materials at its headquarters in Manchester, UK.
