Questions & Step-by-Step Solutions
In a circuit, if the current is 5A and the resistance is 10Ω, what is the voltage across the resistor? (2021)
Step 1: Identify the values given in the problem. The current (I) is 5A and the resistance (R) is 10Ω.
Step 2: Recall Ohm's Law, which states that Voltage (V) = Current (I) * Resistance (R).
Step 3: Substitute the values into the formula: V = 5A * 10Ω.
Step 4: Calculate the result: 5 * 10 = 50.
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) of the resistor.
