Wie man umwandelt elektrische Spannung in Volt (V) zu elektrischer Widerstand in Ohm (Ω).
Sie können Ohm aus Volt und Ampere oder Watt, but you can't convert volts zu ohms since volt and ohm units do not measure the same quantity.
Accoderding zu Ohmschen Gesetz, the resistance R in Ohm (Ω) is equal zu the voltage V in Volt (V) divided by the current I in Ampere (A):
R(Ω) = V(V) / I(A)
So ohms are equal zu volts divided by Ampere:
Ohm = Volt² / Ampere
oder
Ω = V² / A
Calculate the resistance in ohms of a resiszur when the voltage is 5 volts and the current is 0.2 Ampere.
The resistance R is equal zu 5 volts divided by 0.2 Ampere, which gleich 25 ohms:
R = 5V / 0,2A = 25Ω
Die Leistung P is equal zu the voltage V mal dem Strom I:
P = V × I
Der Strom I is equal zu the voltage V geteilt durch den Widerstand R (Ohmschen Gesetz):
I = V / R
Also ist die Leistung P is equal zu
P = V × V / R = V 2 / R
Der Widerstand R in Ohm (Ω) is equal zu the square value of voltage V in Volt (V) divided by the power P in Watt (W):
R(Ω) = V 2(V) / P(W)
So ohms are equal zu the square value of volts divided by Watt:
Ohm = Volt²2 / Watt
oder
Ω = V²2 / W
Calculate the resistance in ohms of a resiszur when the voltage is 5 volts and the power is 2 Watt.
The resistance R is equal zu square of 5 volts divided by 2 Watt, which gleich 12.5 ohms.
R = (5V)²2 / 2W = 12,5Ω
