Norton Current Calculator:
Enter the values of thevenin voltage, Vt(V) and thevenin resistance, Rt(Ω) to determine the value of Norton current, In(A).
Norton Current Formula:
Norton Current refers to the equivalent current source in Norton’s theorem, a fundamental principle used in electrical engineering to simplify complex linear circuits.
Norton’s theorem states that any linear electrical network with voltage sources and resistances can be replaced by a single current source in parallel with a single resistor.
This current is equivalent to the short-circuit current that flows between two points in a circuit.
The calculation of Norton current involves determining the current that would flow if the terminals of interest were short-circuited, assuming all independent sources are active while dependent sources retain their dependency conditions.
Norton’s Theorem states that any linear electrical network with voltage sources and resistances can be simplified to a single current source in parallel with a single resistor.
Norton current, In(A) in amperes is calculated by dividing the thevenin voltage, Vt(V) in volts by thevenin resistance, Rt(Ω) in ohms.
Norton current, In(A) = Vt(V) / Rt(Ω)
In(A) = Norton current in amperes, A.
Vt(V) = thevenin voltage in volts, V.
Rt(Ω) = thevenin resistance in ohms, Ω.
Norton Current Calculation:
- Calculate the Norton current for a network with a thevenin voltage of 12 volts across the terminals and a thevenin resistance of 6 ohms:
Given: Vt(V) = 12V, Rt(Ω) = 6 Ω.
Norton current, In(A) = Vt(V) / Rt(Ω)
In(A) = 12 / 6
In(A) = 2A.
- Determine the thevenin resistance, if the Norton current is 4 amperes and the thevenin voltage across the terminals is 16 volts:
Given: Vt(V) = 16V, In(A) = 4A.
Norton current, In(A) = Vt(V) / Rt(Ω)
Rt(Ω) = Vt(V) / In(A)
Rt(Ω) = 16 / 4
Rt(Ω) = 4 Ω.
