Explanation / Answer

Solution:

7) Tthe discharging behaviour is characterise by exponential decay.

=> Using the equation Vc = Vs x e^(-t / RC)

8) As 6 ohm , 12 ohm , 10 ohm are connected in parallel ,

equivalent resistance = 2.857 ohm

current = V / R

=> I = 10 / 2.857

=> I = 3.50 A option C is Right.

9) equivalent resistance = 30 ohm

10) Using ohm's law , V = I*R

=> I = V / R

=> I = 12 / 24

=> I = 0.50 A ( option D)

11) Equivalent resistance = 1.53 ohm

12) As all resistance are connected in parallel so the voltage across 8.0 ohm resistor will be

=> 14 V (option C)
