Draw a flowcharart

Start

Initialize variables: resistorValue, maxVoltage, voltageIncrement, currentVoltage.

Input: Ask the user to input the resistor value $($resistorValue$)$ in the specified range $(20$ to $2000$ ohms$).$

Decision: If the input is outside the range, display an error message, and go back to step $3.$

Input: Ask the user to input the maximum voltage $($maxVoltage$).$

Initialize an empty array to store voltage and power values.

Set currentVoltage to $1.$

Loop: While currentVoltage is less than or equal to maxVoltage:

a$.$ Calculate: Calculate power $($power$)$ using the formula: power $=($currentVoltage$^2)/$ resistorValue.

b$.$ Store: Append the tuple $($currentVoltage$,$ power$)$ to the array.

c$.$ Increment: Increment currentVoltage by voltageIncrement $($set to $1).$

Output: Plot the graph using the array of voltage and power values.
