You have a 1.50 cm diameter sphere that you would like to have plated with chromium metal. How long will it take to electroplate a 50.0 micron thick coating onto the sphere using Cr+3 and a current of 0.750 amps? The density of chromium is 7.2 g/cm3. 1 micron = 1.00×10–4 cm. [hint: Calculate the difference in volume of the coated and uncoated spheres and then use the density information to determine y
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
