Questions & Step-by-Step Solutions

If the voltage across a resistor is 240V and the resistance is 60 ohms, what is the current flowing through it? (2020)
  • Step 1: Identify the voltage across the resistor. In this case, it is 240 volts (V).
  • Step 2: Identify the resistance of the resistor. Here, it is 60 ohms (Ω).
  • Step 3: Use the formula for current (I), which is I = V / R.
  • Step 4: Substitute the values into the formula: I = 240V / 60Ω.
  • Step 5: Calculate the result: 240 divided by 60 equals 4.
  • Step 6: Conclude that the current flowing through the resistor is 4 amperes (A).
