## 1. What is power

• i dunno but IVE GOT THE POWER *cue song*
• the rate of energy transfer measured in watts
• the rate of energy transfer measured in colombs
• the rate of energy transfer measured in joules
1 of 12

## 2. What is the conservation of energy

• Energy is conserved.
• Energy is not lost or gained just transformed into another form
• Energy is not gained but can be lost through heat

## 3. State Ohm's law

• Ohm's law is like Murphy's law but different
• The current through an ohmic device is directly proportional to the pd across it provided the temperature is constant
• The current is proportional to the voltage, as long as its kept low
• The current through an ohmic device is inversely proportional to the pd provided the temperature is constant

## 4. what is the conservation of charge

• the current going into a junction is equal to the current leaving the junction
• when you turn your phone's battery save on
• the energy going into a junction is equal to the energy leaving a junction
• the voltage going into a junction is equal to the energy leaving a junction

## 5. State Newtons 1st Law

• LOL wut?
• An object remains at constant speed always
• An object remains at rest/constant speed as long as nothing else affects it
• The object remains at rest provided no external forces act upon it
