Questions & Step-by-Step Solutions
If a resistor has a resistance of 5 ohms and a current of 2 amperes flows through it, what is the voltage across the resistor?
Step 1: Identify the values given in the problem. The resistance (R) is 5 ohms and the current (I) is 2 amperes.
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 Ω.
Step 4: Calculate the voltage: 2 * 5 = 10.
Step 5: Conclude that the voltage across the resistor is 10 volts.
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.
