What is electical circuits?
It is a way in which electrons from a voltage or current source stream. Electric current stream in a shut way is called an electric circuit. The point where those electrons enter an electrical circuit is known as the source of electrons.
Which electrical protective device is designed to detect a difference in a current between circuit wires and interrupt the circuit and stop the flow of electricity?
A resistor is a device designed to detect difference in current and stop the flow of electricity. On most every type of electric engine or circuit has a resistor.
Why do electrical wires have plastic covering?
Electrical wires have plastic covering as when electric current flows through the copper wires and mistake we hold it so we may get an electric shock.
What effect will occur if the intermediate switch is replaced by a double pole switch?
The circuit will not work. In a three way lighting circuit system the middle switch needs to cross the traveller wires to be effective. A double pole switch in the circuit will just open both traveller wires and disrupt the current flow in both wires. No current flow, no lights.
What is overload current?
A current greater than which a circuit is designed to carry , may melt wires or damage elements of the circuit.This is known as overloading of current.
When the wires are connected to the terminals of the battery what causes electric current in a circuit?
The resistance of the load is what causes an electric current to flow in a circuit.
What is the role of the electric field in the wires of an AC circuit?
The electric field in the wires of an AC circuit helps to push and pull the electric charges back and forth, allowing the flow of alternating current.
What can connect all the components in a circuit so that an electric current can flow?
Wires
When wires are connected to the terminals of a battery. what causes electric current in the circuit?
The electric current in a circuit is caused by the flow of electrically charged particles, typically electrons, through the wires. When the battery is connected, it creates a potential difference (voltage) that pushes the electrons to move from the negative terminal to the positive terminal, creating a continuous flow of current in the circuit.
What is a current circuit?
A current circuit refers to a closed path through which electric current flows. It is formed by connecting various electrical components, such as resistors, capacitors, and inductors, with conducting wires. The current circuit allows the flow of electric charges, usually in the form of electrons, from the power source to the load.
Why an electric connection has 2 wires?
Two wires are needed so that the electric current has a circuit to flow round. For a simple circuit, the voltage between the wires, multiplied by the current in amps, gives the power in watts, which is how fast energy is used up (joules per second). Also, the voltage divided by the current gives the resistance of the load, in Ohms.
How a fuse controls the flow of electric current in a circuit?
A fuse does not control the flow in a circuit, it limits the current in a circuit. If the load in a circuit shorts out the fuse link melts and opens the circuit and stops the current flow and prevents the wires feeding the circuit from melting and catching fire. resist
Why do you experience a shock in an open circuit?
You don't experience a shock in an open circuit. The only time that you can get a shock from an open circuit is when you act as a switch and close the circuit or you ground the circuit hot side to ground with your body. Current has to flow to give you a shock.
Why are two wires used to carry electric current instead of a single wire?
It takes two wires to complete a circuit. They are commonly called a positive and negative. Without a flow of electricity both in and out of an electric item, there will no be a circuit and the item will not work.
What is a complete electric ciruit?
A complete electric circuit is a closed loop through which an electric current can flow. It consists of a power source, such as a battery, wires to carry the current, and a load, such as a light bulb or motor, that operates using the current. If any part of the circuit is broken, the flow of electricity will stop.
What is The complete path of an electric current described as?
The complete path of an electric current is described as a closed loop circuit. This means that the current flows from the power source through a continuous path of conductive materials, such as wires and components, and back to the power source. Without a closed loop, the current cannot flow continuously and the circuit will not work.
What is the pathway for electric current?
Electric current flows from the power source through a circuit. It moves from the positive terminal of the source, through the wires or conductors, to the load (e.g. a lightbulb), and then returns to the negative terminal of the power source to complete the circuit.
