Current is directly proportional to voltage and indirectly proportional to resistance.
Kirchhoff's Current Law
The current entering any point in a circuit is equal to the current leaving that same point.
Kirchhoff's Voltage law
- Around a closed loop, the algebraic sum of all voltages is zero.
- The sum of the voltage drops around a circuit equals the applied voltage.
Ohm's Law & Watt's Law formula
- E= IxR, P/I, sqrt PxR
- I= E/R, P/E, sqrt P/R
- R= E/I, E2 /P, P/I2
- P= I2xR, E2/R, IxE
