WebA. A A. A. refers to the frontal area of the object that is pushing through the liquid (or gas). An aerodynamic Lamborghini, for example, will experience less air resistance than a boxy Volvo. Nevertheless, for a basic simulation, we can consider our object to be spherical and ignore this element. C d. C_d C d. WebSep 2, 2024 · R = V/I. Where, R = resistance. I = current. V = voltage. The Electrical Resistance formula can be calculated using the length and area of a wire. The formula states that the value of resistance through a wire which is directly proportional to the length and inversely proportional to the cross-sectional area. professor of magical studies igg
