A circuit with an impedance of 5 ohms and a voltage of 100 volts has a current flow of 20 A.
The expression of an electronic component, circuit, or system's resistance to alternating and/or direct electric current is called impedance, indicated by the letter Z. Resistance and reactance are two distinct scalar (one-dimensional) phenomena that combine to form impedance, a vector (two-dimensional) variable.
[tex]Z^{}[/tex] = [tex]\frac{V}{I}[/tex]
(for a pure resistor where Z=R,preserving the form of the DC Ohm's law).
[tex]I=\frac{V}{Z}[/tex]
[tex]I = \frac{100}{5}[/tex]
I = 20 A
Therefore, A circuit with an impedance of 5 ohms and a voltage of 100 volts has a current flow of 20 A.
