Hello,
I've got a lot of homework and can't solve following example:
Transistor KFY34 has to switch a load with rated voltage 24V and resistance Rs=60Ω.
a)Solve size o the Ib after switching load.
b)Solve size of current and voltages in the circuit Ib = f(t), Ic= f(t), Ube = f(t) and Uce = f(t) after switching on and switching off.
c)Decide if additional cooling is needed.
KFY34: NPN, h21E = 35 a 125, UCB0 = 70V, UCER = 50V, ICmax = 500 mA, UCES ≈ 1,5V, PC = 800mW
Thanks for any guidance in advance.
