The primary 'differences' are that the solid state controller uses Pulse Width Modulation (PWM) of a fairly constant voltage verses a resistive controller using BIG resistors to drop the battery voltage before sending it to the motor. At full speed running, they will have essentially the same efficiencies. However at lower speeds the resistive controller will waste quite a bit of your precious battery power in the form of heat loss which the solid state controller will not do. The PWM controller turns the voltage on and off very quickly (pulse repetition rate), but when it's off, it's full off and when it's on it's full on. Power output is controlled by how long the pulse is left on (pulse width). There will be no (or very little) power lost to heat (external to the motor). Resistive controllers drop the battery voltage over a stack of resistors to send a lower voltage to the motor to make it run slower, but in the process, all that volage the resistors drop gets lost to heat (Power lost in Watts = Voltage dropped by resistor times current through resistor.) Less loss to heat = more cruise time per charge. There is also the idea that the PWM controller will provide for smoother speed control. The range of speeds is smoothly variable over the range, while in a unit with a so called speed board and resistors, there are "steps" to the variability of speed. Advantage of going to a 48V system verses a 36V system also has to do with the Power formula of Power in Watts = Voltage x Current (amps). Think about a DC motor with a set resistance of say 0.5 Ohms. Current is V/R So 36V/0.5 = 72A 36V*72A=2592W 746W per HP So 2592/746=3.47HP. Do those same calculations using 48V and the final number is 6.17HP. If you have a motor that can actually take it without smoking, the 48V will get you to your next Golf shot much quicker. In practice, I wouldn't advise a voltage change unless you were intending to replace everything.
yes indeed

A resistor reduces voltage in an electrical circuit by converting some of the electrical energy into heat. This process slows down the flow of electricity, resulting in a decrease in voltage across the resistor.
Potentiators works well as a voltage resistor or variable resistor. It is often used for volume controls on a radio, but they can be cumbersome.
All a resistor does is use electrical energy, converting it to heat. so a 10 ohm resistor with 5 volts across it will dissipate 2.5 watts. this will come out as heat, ie, the resistor will get hot.
Yes, but not sure if the parts are interchangeable.
A resistor in a circuit works by impeding the flow of electrical current, which helps regulate the amount of current passing through the circuit. This is achieved by converting electrical energy into heat energy as the current passes through the resistor, limiting the flow of electricity.

You should care about resistor temperature increase because it can lead to changes in the resistor's electrical properties, such as resistance value and tolerance. Excessive heat can also reduce the lifespan of the resistor and potentially cause it to fail. Monitoring temperature is important to ensure the resistor operates within safe limits and provides accurate performance.

An integrated resistor is a resistor that is manufactured directly onto an integrated circuit (IC) chip. By integrating the resistor onto the chip, space is saved and electrical performance is improved due to shorter connections. Integrated resistors are commonly used in various electronic devices to help control current and voltage levels.
A thermistor an electrical resistor that resistance changes with temperature. There are two advantages of a thermistors one is it been more sensitive that the RTDÕs and thermocouples and two is has a quick response time.
