What battery to use for a MG996R High Torque Servo?
This servo’s operating voltage is 4.8v - 7.2v. The running current is 6v @ 500mA - 900mA, and the stall current is 2.5A @ 6v.
Now, I plan on using this servo 24/7 on my door lock ( this might be a s …

Why can't you just reduce the current instead of the voltage?
Why does voltage even matter, if it's the current that goes through a circuit? I understand the relationship V = IR (I think) and that increasing the voltage (pressure) will increase the current.
H …

What is the meaning of output voltage and current?
I have a 5V power supply with DC output rating: 5V @ 1500mA. It could power my High Torque servo very well.
I, however, have a fairly used 9V Alkaline battery. I shorted this battery and I measured t …
