PHYSICS EQUATIONS

CHARGE
Annotations:
- the amount of negative electrons in a circuit
1. Charge = current x time
  Annotations:
  - C = I x t
RESISTANCE
Annotations:
- anything that opposes the current
1. Resitance = voltage / current
  Annotations:
  - R = V / I
S.L. Heat Energy
1. Energy = mass x S.L.H
  Annotations:
  - E = mL
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
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
2. power = energy / time
  Annotations:
  - P= E / t
3. power = current^2 x resistance
  Annotations:
  - P = I ^ 2 x R
