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