When the batteries are connected in parralell, the voltage remains the same as a single battery, but the current capability is doubled. When connected in series, the voltage doubles at the light, but the current remains the same as if a single battery was connected. Ohm's Law E=IxR R=E divided by I I=E divided by R E=Voltage R=Resistance I=Current
Voltage Stabilizer is also called Automatic Voltage Stabilizer or AC Voltage Stabilizer or Voltage Regulator. Actually an automatic voltage stabilizer is designed to automatically maintain a constant voltage level, with protections of equipment against voltage surges, over voltage, under voltage, smoothing impulsive noise.
its internal resistance V/R= A its internal resistance V/R= A
The two resistor voltage divider is used often to supply a voltage different from that of an available battery or power supply. In application the output voltage depends upon the resistance of the load it drives.
What is a card inside a notebook that converts voltage to CPU core voltage?
