Questions & Step-by-Step Solutions
If the current through a resistor is 3A and the resistance is 4Ω, what is the voltage across the resistor?
Step 1: Identify the current (I) through the resistor, which is given as 3A.
Step 2: Identify the resistance (R) of the resistor, which is given as 4Ω.
Step 3: Use Ohm's law formula, which states that Voltage (V) = Current (I) * Resistance (R).
Step 4: Substitute the values into the formula: V = 3A * 4Ω.
Step 5: Calculate the result: V = 12V.
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.
