Part 10: Use of Power by Lightbulbs Investigation 25. Design a simple circuit using one lightbulb and the instructions from step 1.
Set the power source at 20 V. Use the ammeter to determine the total current in
the circuit as an indication of its use of power.
IF
What happens to the bulbs' use of power if you add a second bulb with the same
resistance in series with the first?
Remove the second lightbulb, and then design a parallel circuit using two
lightbulbs that have the same resistance. How does the use of power in the
parallel circuit compare to the use of power in the simple circuit with one
bulb?

What type of nuclear decay causes the atomic number of an element to increase by 1?

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ
