What is the force on a current carrying conductor?
The force on a current-carrying wire in a magnetic field is F = IlB sin θ. Its direction is given by RHR-1.
What is the force on a current carrying wire that is parallel?
Force on a current-carrying wire that is parallel to the magnetic field will be zero.
What happens to two parallel current carrying wires when their currents flow in opposite directions?
Similarly, if you have two parallel wires with current traveling in opposite directions, as you do in the series circuit, then the magnetic fields of the two wires will be traveling in the same direction at the point at which they intersect, and therefore repel each other.
Why do two parallel current carrying wires attract each other?
Two parallel wires carrying currents in the same direction attract each other due to magnetic interaction between two wires carrying currents because the current in a wire produces a magnetic field and the magnetic interaction is of attractive nature when current in the two parallel wires is in the same direction.
What is the force per unit length f l between the two wires?
F/l is the force per unit length between two parallel currents I1 and I2 separated by a distance r. The force is attractive if the currents are in the same direction and repulsive if they are in opposite directions. This force is responsible for the pinch effect in electric arcs and plasmas.
What is a parallel wire?
In a parallel circuit, all components are connected across each other, forming exactly two sets of electrically common points. A “branch” in a parallel circuit is a path for electric current formed by one of the load components (such as a resistor).
Is it possible for the middle wire to be repelled by both wire 1 and wire 3 Why?
The middle wire can’t be attracted or repulsed by both wires simultaneously, if one is attractive, the other is repulsive.
Is it better to wire in parallel or series?
Wiring Multiple Speakers They are as follows: Series – When you wire (hook-up) speakers in Series, the speakers resistance (as measured in ohms) is additive – i.e. putting two 8 ohm speakers in Series results in a 16-ohm load. Parallel – When wiring in parallel, the resistance of the speakers decreases.
Which circuits are commonly used in homes?
Most standard 120-volt household circuits in your home are (or should be) parallel circuits. Outlets, switches, and light fixtures are wired in such a way that the hot and neutral wires maintain a continuous circuit pathway independent from the individual devices that draw their power from the circuit.
What is advantage of series circuit?
Advantages: 1. Series circuits do not overheat easily. This makes them very useful in the case of something that might be around a potentially flammable source, like dry plants or cloth. The current that flows in a series circuit has to flow through every component in the circuit.
What are the 3 main characteristics of a series circuit?
In summary, a series circuit is defined as having only one path through which current can flow. From this definition, three rules of series circuits follow: all components share the same current; resistances add to equal a larger, total resistance; and voltage drops add to equal a larger, total voltage.
What are the three important characteristics of an electric circuit?
A circuit is the path that an electric current travels on, and a simple circuit contains three components necessary to have a functioning electric circuit, namely, a source of voltage, a conductive path, and a resistor. Circuits are driven by flows.
Where are series circuits used in daily life?
Series circuits are used in areas where the operation of the circuit is required to be linear. Water heaters use a series circuit. Freezers and refrigerators both use series circuits. Lamps also operate on a series circuit.
What’s a real life example of series circuit?
The most common series circuit in everyday life is the light switch. A series circuit is a loop that is completed with a switch connection sending electricity through the loop. There are many types of series circuits. Computers, televisions and other household electronic devices all work through this basic idea.
What are some examples of circuits in daily life?
Freezers and refrigerators both use series circuits. The elements in this circuit are the compressor and the temperature control switch. If the temperature inside the freezer or refrigerator gets too hot, the temperature control switch will turn the compressor on until the temperature drops.
Where are circuits used?
An electric circuit includes a device that gives energy to the charged particles constituting the current, such as a battery or a generator; devices that use current, such as lamps, electric motors, or computers; and the connecting wires or transmission lines.
What are the four most important characteristics of an electric circuit?
Every electric circuit, regardless of where it is or how large or small it is, has four basic parts: an energy source (AC or DC), a conductor (wire), an electrical load (device), and at least one controller (switch).
What is the property of current?
Properties of Electric Current We know that electric current is the result of the flow of electrons. The work done in moving the electron stream is known as electrical energy. The electrical energy can be converted into other forms of energy such as heat energy, light energy, etc.
How is electrical current measured?
Current can be measured using an ammeter. Electric current can be directly measured with a galvanometer, but this method involves breaking the electrical circuit, which is sometimes inconvenient. Current can also be measured without breaking the circuit by detecting the magnetic field associated with the current.
