If a circuit has a current of 2 A flowing through a resistor of 5 ohms, what is the voltage across the resistor?
Correct Answer: 10 V
Step 1: Identify the values given in the problem. We have a current (I) of 2 A and a resistance (R) of 5 ohms.
Step 2: Recall Ohm's Law, which states that Voltage (V) = Current (I) * Resistance (R).
Step 3: Substitute the values into the formula: V = 2 A * 5 ohms.
Step 4: Calculate the result: 2 A * 5 ohms = 10 V.
Step 5: Conclude that the voltage across the resistor is 10 V.
Ohm's Law – Ohm's Law states that the voltage (V) across a resistor is equal to the current (I) flowing through it multiplied by the resistance (R) of the resistor.
