For t = 0 in RC circuit,
After t = 0+ condition, capacitor is behave as short circuit.
Voltage across the it 0.
At final time,
Capacitor is behave as open circuit, voltage across the capacitor at final time is equal to 15 V.
Capacitor opposes the change of voltage.
Conductor with 75 °C temperature rating must have ampacity from the 60°C column or the 75°C column.
It is permissible to use the 75°C rating if the installed conductor is rated at least 75 °C.
Because all of the connection points in this example have at least a 75°C rating, the conductor’s ampacity can be based on the 75°C column
Class B trip curve:
The MCB with class B trip characteristics trips instantaneously when the current flowing through it reaches between 3 to 5 times rated current. These MCBs are suitable for cable protection.
Hence, For 16 A current Type B MCB disconnect fault at 3*16 = 48 A to 5*16 = 80 A.
Equation is given by:
Efficiency = (F.F*Voc*Isc)/Pin
% efficiency = 14.7 %
Z = √(L/C)
C = L/Z²
C = 50*10⁻⁹/(50*50)
C = 0.02 nF
C = 20 pF
