## Illuminance when Effective Intensity is Given Solution

STEP 0: Pre-Calculation Summary
Formula Used
illumination_1 = (Instantaneous Intensity*Threshold Illuminance)/Effective Intensity
E = (I*E0)/Ie
This formula uses 3 Variables
Variables Used
Instantaneous Intensity - Instantaneous Intensity of Light (Measured in Lux)
Threshold Illuminance - Threshold Illuminance for a steady burning Light. (Measured in Lux)
Effective Intensity - Effective Intensity of Light (Measured in Lux)
STEP 1: Convert Input(s) to Base Unit
Instantaneous Intensity: 50 Lux --> 50 Lux No Conversion Required
Threshold Illuminance: 100 Lux --> 100 Lux No Conversion Required
Effective Intensity: 50 Lux --> 50 Lux No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
E = (I*E0)/Ie --> (50*100)/50
Evaluating ... ...
E = 100
STEP 3: Convert Result to Output's Unit
100 Lux --> No Conversion Required
FINAL ANSWER
100 Lux <-- Illumination
