Question

If V_m and I_m are peak voltage and current, impedance Z in an AC circuit is ______.

पर्याय

• `"V"_"m"/"I"_"m"`

• `"V"_"m""I"_"m"`

• `"V"_"m"/(2"I"_"m")`

• `(2"V"_"m")/"I"_"m"`

Answer 1

If V_m and I_m are peak voltage and current, impedance Z in an AC circuit is `underline("V"_"m"/"I"_"m")`.

Explanation:

Impedance The overall obstacle to the passage of current offered by a circuit incorporating various components is referred to as Z. Z also has the same unit as resistance. So, using the ohm's law as an illustration, we get the following relationship:

Z = `"V"_"m"/"I"_"m"`
