A circuit that has more than one path for the current to flow is a parallel circuit. The circuit must have two or more paths to be considered parallel.
A circuit that has only one current path through multiple components is a series circuit.
A circuit in which there is more than one path for current to flow is called a parallel circuit,
parallel circuit
Parallel Circuit
Because there is only a single path in series circuit and many paths in parallel circuit.
It depends on your proximity to the circuit under consideration and your electrical relationship to it. If your body is a part of the circuit, and the current happens to flow through or near your heart, then as little as 0.015 Amp can ... as they say ... cause death. If, on the other hand, you are not a part of the circuit and the current does not flow through you, then there is no danger regardless of the magnitude of the current.
series circuit
An RC CB is a Residual Current Circuit Breaker. It is another name for something more commonly known as an RCD (Residual Current Device). An EL CB is an Earth Leakage Circuit Breaker. It is another name for something more commonly known as a GFCI (Ground Fault Circuit Breaker). For more information on these electrical safety and circuit protection devices please see the answer to the Related Question shown below.
The heat observed in a circuit is the result of electrical resistance.Under normal circumstances, every electrical circuit has a certain amount of resistance to the flow of electricity. Electronflow opposed by the physical nature of the conductor. This is the fundamental nature of electrical resistance. Whenever this happens, the energy of those electrons is absorbed by the conductor (as opposed to flowing through) which then emitts this captured energy as heat. The higher a conductor's resistance, the more electrical energy is converted to heat by it.
A circuit in which electricity only flows in one path is called a series circuit.
A parallel circuit is an electrical circuit that has more than one current branch.
All the components in a circuit have a potential effect on the total current used by the circuit. You have to be more specific to get a more precise answer.
logic circuit
yes
Voltage remains constant; current increases.
Because there is only a single path in series circuit and many paths in parallel circuit.
The resistance of the electrical conductor, eg a wire, reduces the current which can flow in the circuit. The remaining current which does flow generates heat, representing the electrical energy which has been lost in overcoming the resistance.
An 'overcurrent' can be an 'overload current' or a 'short-circuit current'. An overload current exists when the load connected to a circuit draws more current than the circuit is designed to carry continuously. A short-circuit current is a high current resulting from a fault between a line conductor and the neutral conductor or earth.
Parallel circuit
The correct name is a Short Circuit.
A short circuit is when the current in a circuit flows directly from the live/phase conductor to the neutral conductor without passing through a load. This is dangerous because the amount of current in a circuit is determined by the resistance/impedance (assuming constant voltage). The resistance of the conductor is very low and this allows large amounts of current to flow which should operate the circuits protective device (fuse). In the absence of a protective device the current will cause the conuctor toheat up first producing fumes from burning insulation and eventually seting on fire.
