Questions & Step-by-Step Solutions

What is the potential difference across a 5 Ω resistor carrying a current of 2 A?
  • Step 1: Identify the values given in the problem. We have a resistor with a resistance of 5 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 = 2 A * 5 Ω.
  • Step 4: Calculate the result: 2 * 5 = 10.
  • Step 5: Conclude that the potential difference across the resistor is 10 volts (V).
