Electrical field ...
is a region where electrical substance will experience electromagnetic force
is a region around the electrical charges will electromagnetic forces
is a region where electrical substances will experience electrical force
Why the positive and negative charges show the above result?
Same charges attract to each other and different charges repel to each other
Same charges repel to each other and diffrerent charges attract to each other
The line around the negative charges shows the
Electrical forces of the positive charge
Electromagnetic forces of the positive charge
Electrical forces of the negative charge
The electrical lines in the centre of negative charge are highly concentrate. This means ....
The electrical forces in the centre are weaker
The electrical forces in the centre are stronger
The electromagnetic forces in the centre are stronger
The electromagnetic forces in the centre are weaker
In normal situation the candle flame is simetri as shown above because ...
The positive and negative charges inside the flame spread evenly
The positive and negative charges inside the flame stick together
The positive and negative charges not present in the flame
Why the candle flame become unbalanced once the EHT of the circuit switch on?
The positive charges are heavier than negatives charges then they pull almost all the flame towards positive terminal
The positive charges are heavier than negatives charges then they pull almost all the flame towards negative teminal
The negative charges are heavier than positives charges than then they pull almost all the flame towards positive terminal
The negative charges are lighter than the positive charges then they pull almost all the flame towards negative teminal
Why there are electrical charges produced inside the flame?
The flame get electrical charges from the body of candle
The flame get the electrical charges from the match stick that light it up
The friction between the flame and air particles produce electrical charges
What happen in the X region?
Its a neutral region
It belongs to negative charges region
Its a border line between positive charges
What happen to electrical charge when you placed it in X region?
Nothing
Moving upward
Moving downward
Swing to the left and right
Which of the following is correct.
What causes the lightning strike ?
Due to opposite charges on the ground and cloud attract to each other
Due to same charges on the ground and cloud attract to each other
Due to opposite charges on the ground and cloud repel to each other
Due to same charges on the ground and cloud are repel to each other
Solve the problem.
4 C
-4 C
14 C
-14 C
Unit for electrical charge is
Coulomb, C
Ampere, A
Volt, V
Kilo Joule, kJ
What happen to the pingpong ball once it touched the negative terminal
Negative charges inside it is neutralised by the positive charge.
Caused it to become positive. Now positive and negative charge atrract to each other.
The pingpong ball stop swinging
Positive charges inside it is neutralised by the negative charge and cause the ball become negative.
Now same charge. And it will repel.
Swing to positive terminal.
