Hi,
I am trying to learn basic electronic concepts. Voltage divider produces the output voltage which is lower than the input voltage. If am making a circuit where I use 9V battery but the load uses only 5 volts, whats the way to reduce voltage. Voltage divider or Voltage Regulator like LM78M05? Which one should be the way to go and why?
Also...
If I am trying to light a led. I am using 9V battery. I would use respective resistor to limit the current. But I would also need to reduce the voltage using voltage divider or voltage regulator, right?
Resistor limits the current. Whereas current divider reduces the current. Which one to use in what case?
Thanks!
