Electric Circuits and Ohm's Law


In our physics class this week, we started a new topic called electric circuits. Although we have just begun, our teacher informed us that we will have a test on this topic next week. So far, we have been focusing on understanding and memorizing the formulas related to electric circuits, particularly Ohm's Law for the total circuit. Here are some possible questions that may be asked on the test and how to solve them:

  1. Calculate the total resistance of a series circuit:

    • Write down the resistance values of each component in the circuit.
    • Add up all the resistance values to find the total resistance.
  2. Find the current flowing through a parallel circuit:

    • Determine the resistance values of each branch in the circuit.
    • Use Ohm's Law (I = V/R) to calculate the current in each branch.
    • Add up the currents in each branch to find the total current.
  3. Calculate the voltage across a resistor in a series circuit:

    • Determine the resistance value of the specific resistor.
    • Measure the total current flowing through the circuit.
    • Use Ohm's Law (V = I * R) to calculate the voltage across the resistor.
  4. Determine the power dissipated by a resistor in a circuit:

    • Measure the current flowing through the resistor.
    • Measure the voltage across the resistor.
    • Use the formula P = I * V to calculate the power dissipated.
  5. Calculate the equivalent resistance of a parallel circuit:

    • Determine the resistance values of each branch in the circuit.
    • Use the formula 1/Req = 1/R1 + 1/R2 + ... + 1/Rn to calculate the equivalent resistance.

Remember to practice solving various circuit problems using Ohm's Law and the formulas you have learned. Additionally, make sure to understand the concepts behind electric circuits, such as series and parallel connections, voltage, current, and resistance. Good luck with your test!
