Q
Q: If a circuit has a current of 3 A and a resistance of 4 ohms, what is the voltage across the circuit?
Solution:
Using Ohm's Law, V = IR = 3 A * 4 Ω = 12 V.
Steps: 6
Show Steps
Step 1: Understand that we need to find the voltage (V) in the circuit.
Step 2: Recall Ohm's Law, which states that Voltage (V) = Current (I) * Resistance (R).
Step 3: Identify the values given: Current (I) is 3 A and Resistance (R) is 4 ohms.
Step 4: Substitute the values into the formula: V = 3 A * 4 Ω.
Step 5: Calculate the result: 3 * 4 = 12.
Step 6: Conclude that the voltage across the circuit is 12 V.
