An electromotive force responsible for the flow of current.
Answers
Answer:
yes from negative 2 positive terminal
Answer:
When two bodies at different potentials are linked with a wire, free electrons stream from Point 1 to Point 2, until both the objects reach the same potential, after which the current stops flowing. Until a potential difference is present throughout a conductor, current runs.
From the above analogy, we can define electromotive force and voltage as follows:
Electromotive Force Definition: Electromotive force is defined as the electric potential produced by either an electrochemical cell or by changing the magnetic field.
Voltage Definition: Voltage is defined as the electric potential difference between two points.

Types of Current Electricity
There are two types of current electricity as follows:
Direct Current (DC)
Alternating Current (AC)
Direct Current
The current electricity whose direction remains the same is known as direct current. Direct current is defined by the constant flow of electrons from a region of high electron density to a region of low electron density. DC is used in many household appliance and applications that involve a battery.
Alternating Current
The current electricity that is bidirectional and keeps changing the direction of the charge flow is known as alternating current. The bidirectionality is caused by a sinusoidally varying current and voltage that reverses directions, creating a periodic back and forth motion for the current. The electrical outlets at our home and industries are supplied with alternating current.
