Questions & Step-by-Step Solutions
A circuit has a 15V battery and a total resistance of 5Ω. What is the total current flowing through the circuit? (2023)
Step 1: Identify the voltage of the battery, which is 15V.
Step 2: Identify the total resistance in the circuit, which is 5Ω.
Step 3: Use Ohm's law formula, which is I = V / R, where I is the current, V is the voltage, and R is the resistance.
Step 4: Substitute the values into the formula: I = 15V / 5Ω.
Step 5: Calculate the current: 15 divided by 5 equals 3.
Step 6: Conclude that the total current flowing through the circuit is 3A.
Ohm's Law – Ohm's Law states that the current (I) 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.
