We know, electric current flows from the phase wire to the power load. So, to block the current right at phase wire switches connected to a phase wire.
a. Live wire and neutral wire.
b. AC and DC.
c. Filament and...
An inverter is an electric device that changes AC into DC and vice versa. It is used to convert AC source to DC source or DC source to AC source.
A battery charger is a device that is used to put energy into a secondary cell or rechargeable cell by forcing an electric current through it.
It is used to charge the battery of the mobile phone, automobile, laptop, etc.
A transformer that converts high voltage AC to low voltage AC is called step-down transformers.It is used at the power sub-station to decrease the AC voltage before distribution.
A transformer is a device that converts high voltage AC to low voltage AC of the same frequency and vice versa The function of the step-up transformer is that it converts the low voltage of current to high voltage.
A current-carrying wire exerts a force on a magnetic compass and defects it from its usual north-south position which is called the motor effect.
When current is passed through a conductor, a magnetic field is developed around it.
