Voltage

Symbol: V

Unit: Volt

 Symbol for Volt: V

Voltage (potential difference) is the difference in the amount of electrical energy between two points in a circuit.

Examples:

• Voltage = 5 volts
  
• V = 5 V
  

Another definition of voltage 

Energy is measured in joules J. The number of joules that each coloumb ( batch of electrons) gives to a component is known as volt. 1 V = 1 J/C

Homework

• Read 9.8 + 9.9
• Do the yellow block exercises of 9.8 and work book
• Do the yellow block exercises of 9.9 and workbook

 

I = V / R (Current = Voltage Divided by Resistance)

I : current, unit Ampere

V: Voltage, unit volt

R: Resistance, Unit Ohm:

Ω
