Is impossible to change the voltage across a capacitor instantly as this would produce current? Answer : Yes, it's true that you can't change the voltage across a capacitor instantly, and here's why: A capacitor stores energy in the form of an electric field created by the separation of ... is impractical. This is why, in practice, the voltage across a capacitor changes gradually, not instantly....

Solve the following using Taylor’s Series Method (up to 3 terms): \[ \frac{dy}{dx} = x^2 + y, \quad y(0) = 1 \] Find \( y(0.2) \). Answer : #### **Solution:** 1. **Taylor Series Expansion:** The Taylor series expansion of \( y(x) \) around \( x = 0 \) is: \[ y(x) = y(0) + x \frac{dy}{dx} \bigg|_{x=0} + \frac{x^2}{2!} \frac{d^2y}{dx^2} \ ... + 0.004 \] \[ = 1.224 \] **Final Answer: \( y(0.2) \approx 1.224 \)**. ---...
