Resistor cross section
WebThe carbon composition resistor is a type of fixed resistor that reduces or restricts the electric current flow to a certain level. These resistors are the most commonly used resistors in the 1960’s and earlier. However, now-a-days, carbon composition resistors are rarely used because of its high cost and low stability. WebMar 30, 2024 · This Area of Circle is called Area of Cross Section of the Wire Resistance of a conductor is inversely proportional to its area of cross- section. R ∝ 1/A Suppose a wire is 14 mm thick It means its diameter has 14 mm Radius=Diameter/2=14/2=7 mm Area of Cross Section of Wire= πr 2 Area of Cross Section of Wire= 22/7×7 2
