Most people agree that current flows from the negative (cathode) terminal of the voltage source, through the load, and back to the positive (anode) terminal of the voltage source. This is because it is accepted that current is a flow of electrons.
However, most analyses techniques use the convention that current flows from anode to cathode. It is simply a convention. So long as you are consistent in your usage of signs, you will be OK.
Electricity flows in a circuit to generate a current.
Current flows through a complete circuit.
yes
Yes, in a closed circuit, the current is constant and flows continuously through the circuit.
The current flows from negative to positive.
A circuit breaker is a device used to open a circuit if too much current flows through it.
"circuit"
it will open circuit
True
complex circuit
This is the current flowing in the primary circuit when full-load current flows in the secondary circuit.
