2. A sculptor has asked you to help electroplate gold onto a brass statue. You know that the charge carriers in the ionic solution are gold ions (singly ionized charge: 1.6×1019C), and you've calculated that you must deposit 0.490 g of gold to reach the necessary thickness. How much current do you need to plate the statue in 9.0 hours? Gold is 197g/mol and 1 mol = 6.022x1023 ions. %3D 3. a. Find the equivalent resistance of the 5.0 N 5.0 N 5.0 0 resistor network in the figure. b. What is the power output of the 10 V 100 10 N 5.0 0 battery? C. What is the power dissipated by the top-left 50 resistor? ww ww

Z parameter

The Z-parameters that are the impedance parameters of a two-port network are defined by expressing the two-port voltages V1 and V2 in terms of two-port currents I1 and I2. The Z-parameters are calculated by open circuiting one of the two ports at a time henceforth they are called open-circuit impedance parameters.
