Questions & Step-by-Step Solutions

In a DC circuit, if the total power consumed is 50W and the voltage is 10V, what is the total current flowing through the circuit?
  • Step 1: Understand the formula for power in a circuit, which is Power (P) = Voltage (V) * Current (I).
  • Step 2: Rearrange the formula to find the current (I). This gives us I = P / V.
  • Step 3: Substitute the values into the formula. Here, P = 50W and V = 10V.
  • Step 4: Calculate the current by dividing the power by the voltage: I = 50W / 10V.
  • Step 5: Perform the division: 50 divided by 10 equals 5.
  • Step 6: Conclude that the total current flowing through the circuit is 5A.
