Q
Q: If a 12 V battery is connected to a resistor of 4 ohms, what is the current flowing through the circuit?
Solution:
Using Ohm's Law (I = V/R), I = 12 V / 4 Ω = 3 A.
Steps: 6
Show Steps
Step 1: Identify the voltage (V) from the battery, which is 12 volts.
Step 2: Identify the resistance (R) of the resistor, which is 4 ohms.
Step 3: Use Ohm's Law formula, which is I = V / R, to find the current (I).
Step 4: Substitute the values into the formula: I = 12 V / 4 Ω.
Step 5: Calculate the result: 12 divided by 4 equals 3.
Step 6: Conclude that the current flowing through the circuit is 3 amperes (A).
