you can use a voltage divider or a step-down transformer to lower voltage.
Through a relay or some other kind of high voltage switching device.
The rectifier is what changes your AC into DC that the computer can use. Transformer raises or lowers the voltage. So you have 110 volts AC coming into your computers power supply. The Rectifier circuit in there changes the AC voltage to DC voltage but it is still to high for the computer use. The transformer lowers that voltage down to the various voltages that your computer needs
In a series circuit, the potential voltage across the circuit components adds up to the total voltage of the circuit.
By Kirchhoff's Voltage Law, the sum of the voltage drops around the series circuit will equal the voltage applied to the circuit.
depending at the kind and high at the voltage, or/and the high of the power
In a series circuit, the voltage is the same across all components connected in a series. This is known as the series circuit voltage.
Voltage Rise : The energy added to a circuit. Voltage drop: The energy removed from the circuit.
this is the amount of voltage a circuit can hold.
Voltage is impressed across a circuit. Current flows through a circuit.
In a series circuit, the current remains constant throughout the circuit. The voltage across each component in a series circuit adds up to the total voltage of the circuit.
A mercury battery will provide constant voltage. A voltage regulator circuit will also.
A voltage error circuit is called an error amplifier and happens when there are discrepancies between the voltage output and the reference voltage. A current error circuit happens when there is a disruption of flow in an ammeter.
