yes it does have to be a closed circuit
The work in an electric circuit is done by the flow of electric charge, typically achieved by the movement of electrons through a conductor. Work is done when a voltage is applied to the circuit, causing the electrons to move and transfer energy to the components in the circuit like light bulbs or motors.

If there is only one fan in the circuit then it is in a series circuit. If there is more that one fan then they will be connected in a parallel configuration.
because with no circuit no current can flow.current is important in electricity to produce power to work.
Resistors work by impeding the flow of electric current in a circuit. They do this by resisting the flow of electrons, which reduces the amount of current that can pass through them. This restriction helps to control the amount of current in the circuit, which can be important for protecting components or controlling the overall function of the circuit.
I guess Electric Circuit....
Electric energy powers appliances such as a radio or light bulb. It travels in a CLOSE CIRCUIT.
The switch may be off or there is a break in the wire that stopped the electron flow in the circuit
geyser eletronic circuit
Inside an electric cell, chemical energy is converted into electrical energy. When the cell is part of a complete electric circuit, the electrical energy is then converted into other forms of energy, such as light, heat, or mechanical work, depending on the components in the circuit.
