Questions & Step-by-Step Solutions

If a circuit has a total voltage of 50V and a total resistance of 10Ω, what is the total current flowing through the circuit? (2020)
  • Step 1: Identify the total voltage in the circuit, which is given as 50V.
  • Step 2: Identify the total resistance in the circuit, which is given as 10Ω.
  • Step 3: Recall Ohm's law, which states that current (I) is equal to voltage (V) divided by resistance (R).
  • Step 4: Plug the values into the formula: I = V / R.
  • Step 5: Substitute the values: I = 50V / 10Ω.
  • Step 6: Calculate the result: 50 divided by 10 equals 5.
  • Step 7: Conclude that the total current flowing through the circuit is 5A.
  • Ohm's Law – Ohm's Law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor.
