Question: In an AC circuit, what is the relationship between voltage (V), current (I), and impedance (Z)?
Options:
V = I * Z
I = V * Z
Z = V / I
Z = I / V
Correct Answer: V = I * Z
Solution:
In an AC circuit, the voltage is related to current and impedance by V = I * Z.

Questions & Step-by-Step Solutions
In an AC circuit, what is the relationship between voltage (V), current (I), and impedance (Z)?
Step 1: Understand that in an AC circuit, voltage (V) is the electrical potential difference.
Step 2: Know that current (I) is the flow of electric charge.
Step 3: Learn that impedance (Z) is the total opposition to current flow in an AC circuit, similar to resistance in a DC circuit.
Step 4: Remember the formula that connects these three: V = I * Z.
Step 5: This means that if you know the current and impedance, you can find the voltage by multiplying them.
Ohm's Law in AC Circuits – The relationship between voltage, current, and impedance in alternating current (AC) circuits is defined by the formula V = I * Z, where V is voltage, I is current, and Z is impedance.
