How do you test a closed circuit?
we can make an open circuit by disconnecting the wire or break the circuit and a closed circuit is made by connecting all wires with the contents of the circuits.
What are the three basic features all electric circuits must have?
Three things that an electrical circuit must have to operate is, A) a source. Example- battery B) a line. Example- conducting wires that allow the electricity to pass through and C) a load. Example- A light bulb
What three things are needed to make a complete electrical circuit?
The first part is that you need a power source. The second thing is that you need a load. The third thing is that you need the power cables.
Does a knot in a wire affect an electrical circuit?
The knot adds extra resistance and inductance to the wire, which in most cases will not make a difference to its performance in a normal circuit operating at dc or power supply frequencies.
What are electrical contacts?
Two answers for this question. An electrical contact is any point in a circuit that a wire connects to, such as a screw or terminal block. The term is also used when referring to control circuits. There are contacts inside Relays, Ligthting contators, and motor starters. They can be called N.O. for normally open, and or N.C. for normally closed. They "Make" of "Break" and electrical circuit.
How are the bulbs wires and battery connected?
The equipment is all connected in series with each other to make a complete electrical circuit.
Why can transition metals be used to make electrical wires?
Their high conductivity is why transition metals are used to make electrical wires.
When outside what do you do during earthquake?
make sure your not near any electrical wires or telephone wires
What is the differentiation between single phase and three phase circuit?
This is a simple concept when visualized but can be difficult to understand in written form. Single phase essentially has the same phase or position on the wave throughout the entire circuit. Anywhere you measure along the wires in the circuit the voltage will be at the same phase, maximum, minimum, increasing or decreasing and the will only be two wires, supply and return. Three phase has three wires and each wire will be at a different point or phase on the wave at any given time. This is a more efficient way to transport electricity and connecting between any two of the wires will give a single phase circuit. Three phase is also used with three bulbs to light rotating machinery, this will prevent a strobe effect that can make the machine look like it is not moving. My examples are not perfect but, close enough and an animation of three would make it very obvious.
Element used to make jewelry wires electrical contacts?
cheese
What is a switch's purpose?
A switch is used to make or break an electrical circuit.
What is switch purpose?
A switch is used to make or break an electrical circuit.
What occurs when two adjacent conductors make electrical contact and by pass a portion of the circuit?
That is called a short circuit.
What does a complete circuit need to make electrical devices work?
A source of electrons, a path, and something to use the electrons.
How do you test a closed circuit?
we can make an open circuit by disconnecting the wire or break the circuit and a closed circuit is made by connecting all wires with the contents of the circuits.
What general apparatus anyone require to make a complicated electrical circuit?
A circuit can be classified as a voltage source connected to a load.
Why are transition metals used to make electrical wires?
Because of thier high conductivity
