## Voltage gain when load resistance is connected at the amplifier Solution

STEP 0: Pre-Calculation Summary
Formula Used
voltage_gain = -Common-base current gain.*((1/Load resistance+1/Total resistance in collector)/Total resistance in the emitter)
Av = -α*((1/Rl+1/R)/R)
This formula uses 4 Variables
Variables Used
Common-base current gain.- Common-base current gain. α is related to β common-emitter current gain of a transistor and used for calculations.
Load resistance - Load resistance is the resistance value of load given for the network (Measured in Kilohm)
Total resistance in collector - The total resistance in collector is the opposition offered to the current passing through the collector. (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)
