What is emf in physics?
EMF, or electromotive force, is a measure of the energy provided by a source (such as a battery) to move a unit charge around a closed circuit. It is responsible for driving the flow of electric current in a circuit. EMF is measured in volts.
What does the electric battery do?
If there is a full circuit, it will send current around it.
Which electrical component in a circuit provides energy to drive electric charges around a circuit?
Power source such as a battery if u pluged it in it will supply energy to drive electric charges around a circuit
Can you recharge a truck PC by driving around?
Yes why not, you can recharge your truck PC by driving around. To recharge the PC first the truck battery should be charged. Driving recharges truck battery because every truck has a power generator inside it but you cannot recharge your truck battery if it is not working properly the acid level of the battery should be maintained properly. Better you check your battery before recharging battery.
Where did the energy flowing around the circuit begin, and what is the source of this energy?
The energy flowing around the circuit begins at the power source, which is typically a battery or a power outlet. The source of this energy is the chemical reactions within the battery or the electrical power from the outlet.
What are the similarities between the circulatory system and an electrical circuit?
in order for a circuit to work the whole circuit has to be connected, just like the circulatory system. The heart pumps the blood around the body so that the oxygen in the blood can go around the body to the required organs or muscles. In a circuit the battery pumps the electrons around the circuit so that the bulb is able to work.
What is the open circuit voltage of a fully charged 12 volt battery?
Around 13.5 volts or can be as high as 14 volts.
How do circuits work?
Circuits need 3 things to work. They need a load, (what the power goes on) power source, (the battery) and connectors (the wire inbetween). Circuits use electrons to flow from the negative side of the battery and around the circuit back to the battery. This repeats until the circuit breaks.
From which terminal of a battery are electrons pushed?
electrons come from the negative terminal, then goes around the complete circuit (clockwise) and comes back to the positive terminal. hope that helps!
What supplies the electrons that will flow through the circuit?
The metals making up the circuit contain electrons themselves, and when they are together they form a conduction band (a 'sea' of delocalised electrons moving freely around positive atomic kernels) between the bonded metals. So no electrons are actually 'poured in', they are just pushed around.
How does a battery operated toy work?
the batters sends electrons with energy to power its function, it goes around the circuit created to operate the product.
What is a complete loop that electricity flows around?
A complete loop that electricity flows around is called a circuit. A circuit typically includes a power source (such as a battery), conductive wires, and a load (such as a light bulb or motor) that uses the electrical energy. When the circuit is closed or completed, electricity can flow continuously to power the load.
