Questions & Step-by-Step Solutions
In a circuit with a 15V source and a 5Ω resistor, what is the current flowing through the resistor?
Step 1: Identify the voltage (V) in the circuit. In this case, V = 15 volts.
Step 2: Identify the resistance (R) in the circuit. Here, R = 5 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 = 15V / 5Ω.
Step 5: Calculate the result: 15 divided by 5 equals 3.
Step 6: Conclude that the current flowing through the resistor is 3 amperes (A).
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.
