How do you explain a series and parallel circuit to a child?
Through something when a wire is connected to each end of the battery electrons begin to flow from negative to positive yeah from minus to plus. And this flow of electrons.
What happens to the PD in a parallel circuit?
In parallel circuits: the total current supplied is split between the components on different loops. potential difference is the same across each loop. the total resistance of the circuit is reduced as the current can follow multiple paths.
What is current in series and parallel circuits?
In a series circuit, the current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component. In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.
Is PD the same in a parallel circuit?
When resistors are connected in parallel, they have the same potential difference across them. In other words, any components in parallel have the same potential difference across them.
How do you explain voltage and current to a child?
Voltage is the force that pushes electrons through a circuit to produce electricity. Current is the act of the electrons flowing through the circuit.
What is a current for kids?

What happens to PD in a series circuit?
When two or more components are connected in series, the total potential difference of the supply is shared between them. This means that if you add together the voltages across each component connected in series, the total equals the voltage of the power supply.
What happens to current in parallel?
The current in a parallel circuit splits into different branches then combines again before it goes back into the supply. When the current splits, the current in each branch after the split adds up to the same as the current just before the split.
What is the current in parallel circuit?
Total current in a parallel circuit is the sum of the individual branch currents. This relationship in a parallel circuit is expressed as: IT = I1 + I2 + I3… Whenever more resistances are connected in parallel, they have the effect of reducing the overall circuit resistance.
What is the current in a series circuit?
Since there is only one path for electron flow in a series circuit, the current is the same magnitude at any point in the circuit. The total current in a series circuit is the same as the current through any resistance of the circuit.
How do you find PD in parallel?

What is current explain to kids?
Current is the flow of an electric charge. It is an important quantity in electronic circuits. Current flows through a circuit when a voltage is placed across two points of a conductor. In an electronic circuit, the current is the flow of electrons.
How do you explain current to a child?
A current of electricity is a steady flow of electrons. When electrons move from one place to another, round a circuit, they carry electrical energy from place to place like marching ants carrying leaves. Instead of carrying leaves, electrons carry a tiny amount of electric charge.
What is current in simple words?
Current is the rate at which electrons flow past a point in a complete electrical circuit. At its most basic, current = flow. An ampere (AM-pir), or amp, is the international unit used for measuring current.
What happens to current in a parallel circuit?
Why is PD different in series?
Two identical resistors connected in series will share the potential difference. They will get half each. If resistors connected in series are not the same then the potential difference is larger across the larger of the resistors.
Why is current higher in parallel than in series?
As more and more resistors are added in parallel to a circuit, the equivalent resistance of the circuit decreases and the total current of the circuit increases.
Why does current increase in parallel?
Adding more parallel resistances to the paths causes the total resistance in the circuit to decrease. As you add more and more branches to the circuit the total current will increase because Ohm’s Law states that the lower the resistance, the higher the current.
Is current the same in parallel?
The current flowing through every resistive component in a parallel circuit is neither the same nor constant. We have previously described why it isn’t the same in parallel. It’s because of the division that occurs in branches with dissimilar resistance. Also, the current is not constant.
What is current in a parallel circuit?
A parallel circuit has more than one path for current flow. The number of current paths is determined by the number of load resistors connected in parallel. Total current in a parallel circuit is the sum of the individual branch currents.
Is PD same in series?
Potential difference in a series circuit.
If the resistance are not equal they may have different amounts of potential difference across them but when added up they must always equal the p.d. supplied by the cell.
Why is current different in parallel circuit?
When the total current enters one branch, it splits up into respective branches. The branch currents are lower than the total amount of current. The branch current values depend upon the branch resistance. So, the current is different in parallel circuitry.
How do you explain electricity to a 5 year old?
To help a child understand the properties of static electricity, rub a balloon on your hair or a wool blanket or sweater, and watch how it sticks to the wall for a few moments. Explain that this is an example of negatively and positively charged atoms reacting to each other.
What is current example?
Current is defined as the movement of water in a specific direction. An example of current is when a river moves towards a waterfall. The definition of current is something that is happening now or something that is up to date. An example of current is today’s newspaper.
How does current flow?
Current is flow of electrons, but current and electron flow in the opposite direction. Current flows from positive to negative and electron flows from negative to positive. Current is determined by the number of electrons passing through a cross-section of a conductor in one second.
