To establish an electric current, there are two requirements that must be met. There must be a closed conducting path that goes from the positive terminal to the negative terminal. The second requirement is to have an electric circuit for the energy to move a positive test charge against the electric field.
What else can I help you with?
What additional item do you need to make a complete circuit?
a swich
Do you need a battery to make a circuit?
no, but you do need a power source, such as a cell or a power pack if you do not want to use a battery.
What 4 things do you need to make a circuit?
You actually only need two things to make a circuit. One is a power source, such as a batter, and the other is a conductive metal, e.g. copper wire. All you need to do is touch one end of the metal to one pole of the source, and the other end of the metal to the other pole, then vioala! You have a circuit.
What is essential to make a circuit?
In order to make a circuit, you need a power pack, connecting wires (2 or more) and a load. The load can be something like a lightbulb or any form of a resistor.
What components do you need to make a simple series circuit to light a bulb?
You need a Battery, Light Bulb, Ammeter, Switch.
What are two things required to make electric current flow in a circuit?
you need an electrical supply and a load. nice and simple.
Does Walmart sell closed circuit tv's?
A closed circuit television is like a video camera, it can show input from outside sources, but not input that is broadcast to it. Walmart does sell closed circuit televisions but you need a few componets that will make them closed circuit.
A complete what is needed to make a bulb light up?
To make a light bulb light up, you need a closed electrical circuit. This circuit typically consists of a power source (such as a battery or outlet), wires to carry the electricity, and the light bulb itself. When the circuit is complete and electricity flows through the bulb, it will produce light.
What function in a circuit for a switch?
A switch is a make - break device. Its function is a circuit is to make and break the current flow of the circuit that it is in. This action then starts and stops the load that is connected in the circuit.
Full subtractor circuit using x-or gate?
To make a full subtractor, you need an XOR and a NAND gate.
What materials will you need to make a parallel circuit?
Lightbulb(load),Battery(Power source),Switch,Copper wire
Is there an adapter that will make a 110 volt refrigerator receptacle into a 220 volt?
No. You need to rewire the circuit from the electric panel.
