Hi im struggling to understand how you would sketch DC component Va and AC component va for the following questions. Could you show me how on both questions so i understand how to do it on different scenarios. thank you.Also is there like a universal formula i can use as every graph is not the same. Also can u show how to identify the period of each graph.

Question 8. 12V in R₁ A R₁ 5 V C R₂2 w R₂ 4 Consider the circuit below, where the capacitor is uncharged, and the switch is open. The different elements of the circuit have the following values: R₁ = 22, R₂ = 22, R3 = 422, R₁ = 82, R₁ = 82 and C = 10 µF. What is the current I₁ in the circuit when the switch is moved to position 1? Enter your answer, in Amps, in the box below. The answer is acceptable within a tolerance of 0.1 A. h₁: R3 After a long time that the switch has been closed, what is the voltage Vc across the capacitor? Enter your answer, in Volts, in the box below. The answer is acceptable within a tolerance of 0.1 V. Vc:

You are investigating the electrical testing circuits and find that, in an inductive circuit, the relationship between instantaneous current i (amps) and the time t (secs) is given by:    i = 12.5(1-e-t/CR)   You have been asked to determine the time taken for the current to rise from 1 to 2 amps given your own R and C values as follows. R= 140 C= 90
