How many seconds would it take to deposit 17.3 g of ag (atomic mass = 107.87) from a solution of agno3 using a current of 10.00
Brums [2.3K]
Data Given:

Time = t = ?

Current = I = 10 A

Faradays Constant = F = 96500

Chemical equivalent = e = 107.86/1 = 107.86 g

Amount Deposited = W = 17.3 g

Solution:
             According to Faraday's Law,

                                          W  =  I t e / F

Solving for t,

                                          t  =  W F / I e
Putting values,
                                          t  =  (17.3 g × 96500) ÷ (10 A × 107.86 g)

                                          t  =  1547.79 s

                                          t  = 1.54 × 10³ s

Leonard designed a parallel circuit to light two light bulbs. But his circuit doesn’t work. Which two items in the circuit must
klasskru [66]

Answer : When a parallel circuit is built the voltage across each of the components remains the same, also the total current passed is the equal to sum of the currents passing through each components in the circuits.


When 2 or more components are tried to be connected in parallel they maintain the same potential difference (in voltage) across their ends of the circuit.


The potential differences across the components are the observed to be same in magnitude, and they have identical polarities between them.


Then, this same voltage is applicable to all circuit components connected in parallel.


So, if each bulb is wired to the battery in a separate loop, the bulbs will be in parallel series.
