Questions & Step-by-Step Solutions
If a circuit has a total impedance of 6Ω and a current of 2A, what is the voltage across the circuit?
Step 1: Identify the values given in the problem. We have total impedance (Z) of 6 ohms (Ω) and current (I) of 2 amperes (A).
Step 2: Recall Ohm's Law, which states that Voltage (V) equals 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 6Ω: V = 2A * 6Ω.
Step 4: Perform the multiplication: 2 * 6 = 12.
Step 5: Conclude that the voltage (V) across the circuit is 12 volts (V).
Ohm's Law – Ohm's Law states that the voltage (V) across a circuit is equal to the current (I) flowing through it multiplied by the impedance (Z) of the circuit.
