DIFFERENTIATION
- i= ????
- Calculate the current at t= 0.5s
- The total charge entering a terminal is given by Q= 5t sin 4πt mC.
- The total charge entering a terminal is given by Q= 5t sin 4πt mC.
- Calculate the current at t= 0.5s
- 1. Take out all the
information given;
- i= d/dt (5t sin 4πt) mC/s
- t= 0.5s
- v= sin 4πt
- du/dx= 4π cos 4πt
- Q= (5t) (4π cos 4πt) + (sin 4πt) (5) mA
- Q= 20 πt cos 4πt + 5 sin 4πt mA
- Q= 20 πt cos 4πt + 5 sin 4πt mA
- Q= (5t) (4π cos 4πt) + (sin 4πt) (5) mA
- du/dx= 4π cos 4πt
- u= 5t
- v= 5
- v= 5
- t= 0.5s
- i= d/dt (5t sin 4πt) mC/s
- if t= 0.5s ???
- substitute t with 0.5
- Q= 20 π (0.5) cos 4(0.5) π + 5 sin 4(0.5) π
- Q= 10π cos 2π + 5 sin 2π mA
- Q= 10π mA
- Q= 20 π (0.5) cos 4(0.5) π + 5 sin 4(0.5) π
- substitute t with 0.5
