How big is the collector current of a transistor with 100 beta if the serial base resistance is 1Kohm and 1V falls on it?

To calculate the collector current (Ic) of a transistor, we first need to determine the base current (Ib). With a base resistance (Rb) of 1 kΩ and a voltage drop of 1 V across it, the base current is Ib = V/Rb = 1V / 1000Ω = 1 mA. Given that the transistor has a current gain (beta) of 100, the collector current is Ic = beta × Ib = 100 × 1 mA = 100 mA.
