## Small signal voltage in terms of resistance Solution

STEP 0: Pre-Calculation Summary
Formula Used
small_signal_voltage = Input resistance*(Emitter Resistance/Emitter Resistance+Total resistance in the emitter)
vπ = Rin*(re/re+R)
This formula uses 3 Variables
Variables Used
Input resistance - The input resistance is the resistance seen by the current source or voltage source which drives the circuit. (Measured in Ohm)
Emitter Resistance - Emitter Resistance is a dynamic resistance of the emitter-base junction diode of a transistor. (Measured in Ohm)
Total resistance in the emitter - The total resistance in the emitter is the total opposition caused in the flow of current in the emitter (Measured in Ohm)
STEP 1: Convert Input(s) to Base Unit
Input resistance: 25 Ohm --> 25 Ohm No Conversion Required
Emitter Resistance: 50 Ohm --> 50 Ohm No Conversion Required
Total resistance in the emitter: 40 Ohm --> 40 Ohm No Conversion Required
