A battery or an emf device creates an electric force field that moves electrons through a circuit. The emf device has two terminals, a positive terminal called anode and negative terminal called cathode.
A battery or an EMF device
Answer is A.
An electric force field is provided by an energy source such a cell or a battery. A potential difference is created when a conducting wire is connected across the two terminals of the battery. This creates an electric force field which pushes the electrons from one towards the another. The flow of electrons constitutes an electric current.
a. energy source
In a circuit, there is cell or battery. This is the energy source. The battery creates an electric force field which causes electrons to move through the circuit. The current moves from positive terminal to negative terminal of the battery.
Resistance opposes the current in the circuit. load is same as resistance. Metal wires are used to connect different components of a circuit.
A. energy source
An energy source like a batter or emf can move electrons through the circuit of what it's connected to and provide a force field (the case of the battery)
A battery or an emf device creates an electric force field that moves electrons through a circuit. The emf device has two terminals, a positive terminal called anode and negative terminal called cathode
The correct anwser is A!
1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":
on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.
remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.
the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
