|
when electron is moving the same direction as field...
|
No force is acting on it so force will be zero
|
|
|
when distance between plates are halved...
|
force on electron doubles as electric field doubles and therfore KE is the same
|
|
|
when we double the voltage...
|
current will also double as P=V^2/R
|
|
|
when a resistor is removed...
|
total resistance will increase and total current will increase where the current and voltage for the other resistors will DECREASE
|
|
|
when two wires that are cutting across field and same direction...
|
current in wire will become zero and as each wire has same voltage across it and in opposite directions, voltage =0
|
|
|
when there is current going through a wire/rod and is in magnetic field...
|
it will experience a force, making it move/ electrons cutting through magnetic field so force is acting on it
|
|
|
when electromagnetic force is produced from induced current....
|
force is opposite direction to the movement so rod/wire will slow down and stop
|
|
|
when a object touches a charged plate it will
|
gain or lose electrons until it becomes charged and will experience a force where it will go to plate of opposite charge
|
|
|
when an electron cuts a magnetic field
|
it is experiencing a force (in a particular direction)
|
|
|
when resistance is low... when resistance is infinite/large
|
current is large
current is 0 |
