Electrical Charge unit
Law of Conservation of Electrical charge
:You can never create an electrical charge, it moves from one place to the other.
Kirchhoff loop= Series
-The current is the same throughout the whole loop, the resistance is added together.
Like Charges repel and unlike charges attract
Columb's law
:kq1q2/r^2
Constant
:k=9x10^9 Nm^2/C^2
Ohms law
:I=v/R or V=I*R
Kirchhoff junction= parallel
-The current divides itself to each loop, it goes to each bulb seperately.
Terminal voltage:
value hat is less than EMF potential, it is when you measure the actual voltage between the terminals of the battery.
Power expression
: P=I*V
Insulator
: no transfer
Conducter
:transfer
Positive and Negative charges are the two tpes of charges
Resistance
=R= ratio of voltage
Current
=I= amount of charge
Voltage
=V =amount of energy
I=A-q/s
Parallel connections
: 1/R+1/R1+1/R2+.....
Junction Rule:
: The total current in
Loop Rule
:The total voltage in
I=q/T
Series:
No branches and resistors have the same electrical current
Parallel:
multiple resistors in seperate loops
