Delimiter between question and answer:

Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

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
What is the direction of the electric current?
It is defined as the flow of charge from the positive terminal to the negative terminal
What happens in case a circuit is closed?
The energy of the power source reaches the load devices and the electricity flows
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
If there are several resistors connected in parallel, what would be the total resistance?
1/R=1/R1 + 1/R2 +.....+ 1/Rn
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
How do you call a circuit formed with the equivalent resistors
Equivalent cicuit
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 draw a series-parallel combination circuit?
...
Can you draw a parallel circuit?
...
Can you draw a series circuit?
...
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
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 the unit of measurement of resistance?
Ohm
What is the unit of measurement of voltage
V or volt
What is the opposition to the flow of the electric current?
Resistance
How do you call the difference in electrical energy between two points?
Voltage
What is the unit of measurement of the current
A, or ampere
What is another word for voltage?
potential difference
What is the name for the amount of electrons that flow through a wire over a certain time?
current
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
What is the voltage of the alternating current in Spain?
230V
Which current is used by the devices plugged into an electricity network?
alternating current
Which current is used by the devices powered by batteries or cells?
Direct current
How do you call an electrical current which value and direction vary cyclically within a circuit?
Alternating current
How do you call the current produced when electrons always move in the same direction inside an electric circuit?
direct current
What is electric current?
A flow of electrons from one atom to another
