If there are two or more resistors connected in series, how do you calculate the total equivalent resistance?

it will be the sum of all the resistors: R=R1+R2+.....Rn

What is the unit of measurement of voltage

V or volt

What is the name of a series of interconnected components that an electric current flows through to produce en effect (e.g. light, heat, sound, movement)

electric curcuit

How do you call the difference in electrical energy between two points?

Voltage

How do you call a circuit formed with the equivalent resistors

Equivalent cicuit

Can you draw a series circuit?

...

What is the name for the amount of electrons that flow through a wire over a certain time?

current

How do you call an electrical current which value and direction vary cyclically within a circuit?

Alternating current

Which current is used by the devices powered by batteries or cells?

Direct current

What is the unit of measurement of the current

A, or ampere

What is the direction of the electric current?

It is defined as the flow of charge from the positive terminal to the negative terminal

Which current is used by the devices plugged into an electricity network?

alternating current

What is the opposition to the flow of the electric current?

Resistance

Can you draw a series-parallel combination circuit?

...

What is a parallel circuit?

In parallel circuit, load devices are connected on different branches and there are several possible paths for the current to flow through

Can you formulate the Ohm's law?

The current going through a conductor between two points is directly proportional to the voltage and inversely proportional to the resistance

What is another word for voltage?

potential difference

What is a series circuit?

it is a circuit in which the resistors are connected one after another, so that electrical current flows through all the load devices

How can you differentiate where the positive and negative contacts are in the devices that run on batteries?

The negative terminal has a metal spring and the positive has a metal plate

How do you call the current produced when electrons always move in the same direction inside an electric circuit?

direct current

What happens if a circuit is open?

The energy of a power source can't reach the load devices, so the electric current can't flow

What is the voltage of the alternating current in Spain?

230V

What is the unit of measurement of resistance?

Ohm

If there are several resistors connected in parallel, what would be the total resistance?

1/R=1/R1 + 1/R2 +.....+ 1/Rn

What happens in case a circuit is closed?

The energy of the power source reaches the load devices and the electricity flows

What is electric current?

A flow of electrons from one atom to another

Can you draw a parallel circuit?
