If a circuit has a current of 5A flowing through a resistor of 10Ω, what is the voltage across the resistor?
Correct Answer: 50V
Step 1: Identify the values given in the problem. We have a current (I) of 5A and a resistance (R) of 10Ω.
Step 2: Recall Ohm's Law, which states that Voltage (V) equals Current (I) multiplied by Resistance (R). The formula is V = I * R.
Step 3: Substitute the values into the formula. Replace I with 5A and R with 10Ω: V = 5A * 10Ω.
Step 4: Perform the multiplication: 5A * 10Ω = 50V.
Step 5: Conclude that the voltage across the resistor is 50V.
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), expressed as V = IR.
