Questions & Step-by-Step Solutions
A 12 V battery is connected to a circuit with a resistance of 4Ω. What is the current flowing through the circuit?
Step 1: Identify the voltage (V) from the battery, which is 12 volts.
Step 2: Identify the resistance (R) in the circuit, 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.
Ohm's Law – Ohm's Law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor.
