Questions & Step-by-Step Solutions

What is the voltage across a 10 ohm resistor carrying a current of 2 A?
  • Step 1: Identify the values given in the problem. We have a resistor with a resistance of 10 ohms and a current of 2 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 * 10 ohms.
  • Step 4: Calculate the result: 2 A * 10 ohms = 20 V.
  • Step 5: Conclude that the voltage across the 10 ohm resistor is 20 V.
