  1. This law states that the total power dissipated in a circuit is the product ofthe voltage applied to the circuit and the total current flowing in the circuit.Therefore,P = VI. Using other forms of Ohm's law, P = I^2*R or P = V^2/R
    Watt's law
  2. This is the term used to describe the rate at which energy is used. In an electrical circuit, it is the heat generated by the circuit components. It is denoted by P and measured in units of Watts (W).
  3. This law states that the algebraic sum of all voltages around a single closed loop is the zero. In other words, the sum of voltage drops across each component equals the total voltage applied to the circuit.
    Kirchhoff's Voltage Law
  4. This is used to designate a circuit that has only one path for the flow of current. The current through each of the resistors in this circuit is the same.The total resistance for this circuit is the sum of the individual resistances.
    Series circuit
  5. This law describes the relationship between the current, voltageĀ  in electric circuits. There are three different ways this law can be expressed:I = V/R, R = V/I and V = IR
    Ohm's law
  6. V = I x R (Voltage = Current x Resistance)
    Ohm's Law Equation
  7. P = V x I (Power = Voltage x Current)
    Power equation
