Q
Q: A circuit has a voltage of 12V and a resistance of 4Ω. What is the current flowing through the circuit?
Solution:
Using Ohm's Law, I = V/R = 12V / 4Ω = 3A.
Steps: 7
Show Steps
Step 1: Identify the voltage in the circuit, which is given as 12V.
Step 2: Identify the resistance in the circuit, which is given as 4Ω.
Step 3: Recall Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R).
Step 4: Write the formula: I = V / R.
Step 5: Substitute the values into the formula: I = 12V / 4Ω.
Step 6: Perform the division: 12 divided by 4 equals 3.
Step 7: Conclude that the current flowing through the circuit is 3A.
