- Please show formula used and steps as I will study themarrow_forwardQuestion One R C ww (t)T Figure 2: R-C Circuit A series R-C circuit in figure 2, has a step input voltage applied to it. Use Laplace transforms to determine expressions for (a) Current, i(t) flowing in the circuit, given that when t = Os, i=0A [12 marks] (b) Use the expression obtained in (a), calculate the current i(t) flowing in the circuit, when V = 15volts, R = 50, C=1F, t = 1sec [2 marks]arrow_forward7. MOSFET circuit The MOSFET in the circuit below has V₁ = 1 V and kn = 4 mA/V². a) Is the MOSFET operating in saturation or in the triode region? b) Determine the drain current ID and Vout. + 5 V 5 k Voutarrow_forward

MOSFET circuit The MOSFET in the circuit below has V₁ = 1 V and kn = 2 mA/V². a) Is the MOSFET operating in saturation or in the triode region? b) Determine the drain current ID. +2V 2 V -2 Varrow_forwardPlease show formula used and steps as I will study themarrow_forward
- please answer question and label accordinglyarrow_forwardQuestion 1: Answer A, 6EH is wrong Question 7: Answer D is wrongarrow_forwardA.With the aid of a diagram, describe fringing, and explain the impact that it has on the relevant magnetic circuit parameter. B. A coil of 1500 turns give rise to a magnetic flux of 2.5 mWb when carrying a certain current. If this current is reversed in 0.2 s, what is the average value of the e.m.f. induced in the coil? C.Define Mutual Inductance.Two coils are connected in series and their total inductance is measured as 0.12 H, and when the connection to one coil is reversed, the total inductance is measured as 0.04 H. If the coefficient of coupling is 0.8, determine:The self-inductance of each coil, and the mutual inductance between the coils.arrow_forward
