Yes, an electric circuit can be completed without connecting it to earth. The circuit needs a complete path for the current to flow back to the source, so as long as the circuit is properly connected and the electrons can flow through the components, it will work without needing an earth connection.
What else can I help you with?
How can you earthed a 3 phase electric circuit?
To earth a 3-phase electric circuit, connect the earth wire from each phase to a common earth point, usually a grounding rod or plate buried in the ground. This helps to protect against electrical faults and ensures the safety of the circuit by providing a path for excess current to flow safely into the ground. It is important to follow local electrical codes and regulations when earthing a 3-phase circuit.
What is used in an electrical circuit to prevent a short current?
A Fuse or a circuit breaker can be used to protect an electric circuit from over loads. A surge arrestor / over voltage relay can be provided for voltage protection An ELCB/ Earth fault Relay may be provided for earth fault protection. Electrix Chennai, India.
What is mean by 4 pole ELMCB?
A 4 pole ELMCB refers to a 4-pole Earth Leakage Miniature Circuit Breaker. It is a type of circuit breaker that trips when it detects a leakage current to ground, protecting against electric shocks or fire hazards. The 4 poles indicate that the ELMCB provides protection for all phases and the neutral wire in a circuit.
Is a circuit electrically grounded if it can carry electric current from a short circuit directly to earth?
Yes, a circuit is considered electrically grounded if it can carry electric current from a short circuit directly to earth. This allows excess current to flow harmlessly into the ground, preventing damage to equipment and potential hazards to people. Grounding also helps in protecting the circuit from overvoltages and surges.
What does short circuit mean?
A short circuit condition is caused by the grounding of the circuit anywhere from the distribution point to the load of a circuit. This grounding causes a high rush of current because of a low resistance of this type of circuit. This high rush causes the over protection device to trip and interrupt the current flow.
Electric fittings are earthed so that?
current may pass to the earth in case of short circuit without any harm.
Why can some birds land on high voltage lines without getting shocked and and some can't?
To get electric shock, the circuit must be completed and the subject who is in the path, or who becomes the path gets shock. When a bird sits on the wire, there is no closed path or circuit hence it does not shock. Same bird while sitting on the wire, and part of its body touches the earth or ground it then will get shock.

What is purpose of the Earth wiring?
When there is too much current flowing through a circuit the earth wire will take the current away and prevent someone from getting an electric shock
In an electric circuit the ground prevents current from flowing in the circuit true or false?
In an electric circuit, the ground does not prevent current from flowing. Instead, it provides a safe path for electrical current to return to the earth in the event of a fault. It's a protective measure to prevent electrical shock hazards by maintaining the voltage stability in the circuit. The normal operation of the circuit isn't affected by the grounding system.
What is clean earthing?
A clean earthing system is a circuitry that connects the electric circuit to the ground. This defines the electrical conductors to the Earth's conductive surface.

What is the purpose of using 3 different colour wires in an electric iron?
The live (blue) wire delivers the power from the mains into the iron's circuit. The neutral (brown) is the return path back to the mains (electricity needs a closed circuit to flow). The earth (green/yellow stripe) wire is a safety device in case anything goes wrong with the wiring in the iron to cause a short circuit. It delivers the power along the earth wire into the ground instead of it going through the user.The Iron would work without the earth wire being connected but the user would be at risk of electric shock if the iron developed a fault or the wires came loose.

What will happen if you place a magnetic compass in an electric curcuit?
Placing a magnetic compass in an electric circuit would interfere with its ability to accurately point to the Earth's magnetic north. The magnetic field generated by the electric current in the circuit would cause the compass needle to deflect from its normal orientation.
What does grounding mean in science?
Same as earthing. Connecting an electric circuit to the ground allows electrons to flow down to earth, and spread out. It therefore acts like an absolute 0V level in the circuit. There are various reasons why one might want to do this.
Why the high resistance earth fault in the appliance increase the risk of electric shock when using appliance in earth situation?
If the earth connection has a high resistance it is not capable of acting as a true earth. For example, the high resistance might mean that the fuse or circuit-breaker will fail to operate when there is a fault.
