PHYSICS EQUATIONS
  1. CHARGE

    Annotations:

    • the amount of negative electrons in a circuit
    1. Charge = current x time

      Annotations:

      • C = I x t
    2. RESISTANCE

      Annotations:

      • anything that opposes the current
      1. Resitance = voltage / current

        Annotations:

        • R = V / I
      2. S.L. Heat Energy
        1. Energy = mass x S.L.H

          Annotations:

          • E = mL
        2. S.H.C

          Annotations:

          • the specific heat capacity is the amount of energy that is required to raise 1kg of a substance by 1 degrees celsius
          1. change in energy = mass x change in temp
          2. POWER

            Annotations:

            • the rate of doing work, the unit for this is joules per second (J/s) more commonly known as a watt.
            1. power= voltage x current

              Annotations:

              • P= V X I
              1. power = energy / time

                Annotations:

                • P= E / t
                1. power = current^2 x resistance

                  Annotations:

                  • P = I ^ 2 x R
