The below mathematical formula is used in this calculator to find the terminal voltage magnitude of the lossless transmission line
The below step by step solved example problem may helpful for users to understand how the input values are being used in such calculations to find the output voltage magnitude with respect to source voltage and characteristic impedance.
Find the terminal or output voltage magnitude of the lossless transmission line whose source voltage Vsrc = 10 kilo volts, source resistance Rsrc = 2 kilo Ω & characteristic impedance Z0 = 7 kilo ohms.
The given data
voltage Vsrc = 10 kilo volts
source resistance Rsrc = 2 kilo Ω
characteristic impedance Z0 = 7 kilo Ω
Step by step calculation
Formula to find Vterm = Vsrc x (Z0)/(Rsrc + Z0)
substitute the values in the above formula
= 10000 x (7000/(2000 + 7000))
Vterm = 7.7 kilo volts
