## Input resistance of the transistor amplifier Solution

STEP 0: Pre-Calculation Summary
Formula Used
resistance = Amplifier input/input current
R = vi/i0
This formula uses 2 Variables
Variables Used
Amplifier input - Amplifier input is a measure of how much an amplifier “amplifies” the input signal. (Measured in Volt)
input current - input current is the current sent to the wire. (Measured in Ampere)
STEP 1: Convert Input(s) to Base Unit
Amplifier input: 50 Volt --> 50 Volt No Conversion Required
input current: 0 Ampere --> 0 Ampere No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
R = vi/i0 --> 50/(0)
Evaluating ... ...
R = NaN
STEP 3: Convert Result to Output's Unit
NaN Ohm --> No Conversion Required
NaN Ohm <-- Resistance
