With a micrometer size detection line in front of the steps according to the inverse we can calculate the wire section area. Such as the 1.5 square single strand of copper wire diameter of 1.38mm, calculation of (1.38/2) * (1.38/2) * 3.14 * 1 = 1.494954 square, this is the ...
V= voltage, electric potential differenceΔ VorE= electromotive force (emf = voltage). Enter any two known values and press "calculate" to solve for the two others. Please, enter only two values. Voltage or voltsEorVvolts V Amperage or currentIamperes, amps A ...
Calculate the mass percentage Now that the equation is complete, solve the mass percentage. Divide the chemical's mass by the compound's total mass and multiply by 100. This allows you to determine the mass as a percentage of chemicals. ...
Therefore, we use the following formula to calculate the value of V: V = I × R 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...
