Temperature of a wire equation
Web9 May 2024 · Substituting the values in the equation, we get V = 3.2 A × 50 Ω = 160 V V = 160V Example 2: An EMF source of 8.0 V is connected to a purely resistive electrical appliance (a light bulb). An electric current of 2.0 … WebFor temperatures above 0°ÊC, the C coefficient equalsÊ0. Therefore, for temperatures above 0°ÊC, this equation reduces to a quadratic. If you pass a known current, I EX , through the RTD and measure the output voltage developed across the RTD, V 0 , you can solve for t: t = 2(V 0 −I EX R 0 ) I EX R 0 [A+A 2 +4B(V 0 −I EX R 0 )/I EX R 0 ] where V 0
