STEP 0: Pre-Calculation Summary
Formula Used
Load Impedance = Characteristic Impedance*(Reflected Voltage+Incident Voltage)/(Incident Voltage-Reflected Voltage)
Il = Z0*(Er+Vi)/(Vi-Er)
This formula uses 4 Variables
Variables Used
Load Impedance - (Measured in Ohm) - The load impedance is defined as the impedance of the load of the Transmission line during transient.
Characteristic Impedance - (Measured in Ohm) - The characteristic impedance of a uniform transmission line is the ratio of the amplitudes of voltage and current of a single wave propagating along the line during transient condition.
Reflected Voltage - (Measured in Volt) - Reflected Voltage is the voltage that is reflected in the transmission line during transient condition.
Incident Voltage - (Measured in Volt) - The Incident Voltage on the transmission line is equal to half the generator voltage.
STEP 1: Convert Input(s) to Base Unit
Characteristic Impedance: 55.5 Ohm --> 55.5 Ohm No Conversion Required
