Kirchhoff's second law
Kirchhoff's Voltage Law or Kirchhoff's Second Law states that “in any closed loop network, the total voltage around the loop is equal to the sum of all the voltage drops within the same loop” which is also equal to zero.
Tesla
The tesla (symbol: T) is the unit of magnetic flux density (also called magnetic B-field strength) in the International System of Units (SI). One tesla is equal to one weber per square metre.
Current x Time
The unit of quantity of electricity is called the coulomb.
A coulomb is the quantity of electricity which passes any point in a circuit in 1 second when a steady current of 1 ampere is flowing. It follows that the total quantity of electricity Q, in coulombs, which passes any point in an electric circuit is given by multiplying the current I, in amperes, by the time t, in seconds.
The formula for Quantity of Electricity (Q) is = Current x Time
