If a 10Ω resistor carries a current of 2A, what is the voltage across the resistor? (2023)
Step 1: Identify the values given in the problem. We have a resistor with a resistance of 10 ohms (Ω) and a current of 2 amperes (A).
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 * 10Ω.
Step 4: Calculate the voltage: 2 * 10 = 20.
Step 5: Conclude that the voltage across the resistor is 20 volts (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.
