Minimum Energy required by Electron to Leave Cathode Solution

STEP 0: Pre-Calculation Summary

Formula Used

Net Energy = Cathode Current Density*Cathode Voltage
Q = J_c*V_c
This formula uses 3 Variables

Variables Used

Net Energy - (Measured in Watt per Square Meter) - Net energy refers to the amount of usable energy obtained from a particular energy source after deducting the energy required to extract, process, and deliver that energy.
Cathode Current Density - (Measured in Ampere per Square Meter) - Cathode Current Density is a measure of the flow of electric charge through a given area of a conductor from Cathode.
Cathode Voltage - (Measured in Volt) - Cathode Voltage is the cathode potential. Cathode voltage refers to the electrical potential difference or voltage at the cathode of an electrochemical cell or device.

STEP 1: Convert Input(s) to Base Unit

Cathode Current Density: 0.47 Ampere per Square Centimeter --> 4700 Ampere per Square Meter (Check conversion here)
Cathode Voltage: 1.25 Volt --> 1.25 Volt No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q = J_c*V_c --> 4700*1.25

Evaluating ... ...

Q = 5875

STEP 3: Convert Result to Output's Unit

5875 Watt per Square Meter -->0.5875 Watt per Square Centimeter (Check conversion here)

FINAL ANSWER

0.5875 Watt per Square Centimeter <-- Net Energy

(Calculation completed in 00.020 seconds)
