"is the pressure that pushes electrons in a circuit."
Graph: V-t
Representation & Unit:
V or E:
1 Volt = 1 Joule / Coulomb
# volt : potential energy required to move 1 Coulomb of charge from one point to another.
Explanation:
This potential energy, stored in the form of an electric charge imbalance and capable of provoking charge carriers to flow through a conductor, can be expressed as a term called voltage, which technically is a measure of potential energy per unit charge or something a physicist would call specific potential energy.
work done by rubbing
work done by pumping
imbalance in electrons create a force
imbalance in height create a force
Terminologies:
Voltage = electron pressure
Voltage Drop = electron pressure drop
Potential Difference = electron pressure difference
Ground = zero electron pressure or reference point electron pressure
# electron pressure developed due to accumulation of electrons at a point and repulsive force b/w them.
Measure:
Remember: Parallel Measurement
Step 1: Multimeter Knob in dc V or mV.
Step 2: Black Probe to Battery's Negative Terminal.
Step 3: Red Probe to Battery's Positive Terminal.
Note: You can hold the terminals with bear hands. It will not give you any kind of electric shock.
Positive, Negative & Zero Voltage Funda:
You are taller. -- No meaning.
Voltage (i.e electron pressure) at a point. --No meaning.
You are taller than Bob. -- Has meaning.
Electron pressure at Red Probe compare to Electron Pressure at Black Probe. -- Has meaning.
Positive Voltage:
Red Probe Electron Pressure > Black Probe Electron Pressure.
Negative Voltage:
Reg Probe Electron Pressure < Black Probe Electron Pressure.
Zero Voltage: (doesn't mean No Electron Pressure)
Red Probe Electron Pressure = Black Probe Electron Pressure.
Experiments:
Measure the positive and negative voltage of any battery with multimeter.
