Questions & Step-by-Step Solutions
In an AC circuit, if the impedance is 5Ω and the current is 2A, what is the voltage across the circuit?
Steps
Concepts
Step 1: Identify the values given in the problem. The impedance (Z) is 5 ohms (Ω) and the current (I) is 2 amperes (A).
Step 2: Recall Ohm's Law for AC circuits, which states that voltage (V) is equal to current (I) multiplied by impedance (Z). The formula is V = I * Z.
Step 3: Substitute the values into the formula. Replace I with 2A and Z with 5Ω: V = 2A * 5Ω.
Step 4: Perform the multiplication: 2 * 5 = 10.
Step 5: Conclude that the voltage (V) across the circuit is 10 volts (V).
