The formula for calculating current draw is: I = P / V, where I is the current in amps, P is the power in watts, and V is the voltage in volts.
The formula for calculating resistance is: R = V^2 / P, where R is the resistance in ohms, V is the voltage in volts, and P is the power in watts.
The unit of measurement for current draw is amperes (amps).
To convert watts to amperes, divide the wattage by the voltage. For example, if you have a 100-watt device with a voltage of 10 volts, the current draw would be 100/10 = 10 amps.
The resistor value can be determined by using the formula R = V / I, where R is the resistance in ohms, V is the voltage in volts, and I is the desired current draw in amps. In this case, the resistor value would be 210 Ω.
