Question

WHAT IS voltage ???

Answer 1

Voltage, electric potential difference, electric pressure or electric tension is the difference in electric potential between two points, which is defined as the work needed per unit of charge to move a test charge between the two points.

Answer

• Voltage, electric potential difference, electric pressure or electric tension is the difference in electric potential between two points, which is defined as the work needed per unit of charge to move a test charge between the two points.

➜ In SI base units: kg⋅m2⋅s−3⋅A−1

➜ Dimension: M L2 T−3 I−1

• Derivations from other quantities:

Voltage = Energy / charge

Calculation

➜ Ohms Law and Power

• To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)
• To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)
• To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)
• To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)

Function

• Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light. In brief, voltage = pressure, and it is measured in volts (V).

Stages

• The conductors between a voltage source and a load are called lines, and the voltage between any two lines is called line voltage. The voltage measured between any line and neutral is called phase voltage. For example, for a 208/120 volt service, the line voltage is 208 Volts, and the phase voltage is 120 Volts.
