Questions & Answers

Q: How does current flow in parallel resistors?

Current from the battery splits at each branch in parallel resistors, with some flowing through each resistor following Ohm's law.

Q: How is current calculated in each branch of a parallel resistor circuit?

Current in each branch is calculated using Ohm's law, dividing the voltage of that branch by its resistance.

Q: Why is the total current equal to the sum of currents in each branch?

The total current in a parallel circuit equals the sum of currents in each branch, following the principle of conservation of charge.

Q: How is the total current calculated in parallel resistors?

The total current in a parallel circuit is calculated using the total voltage of the battery and the equivalent resistance of the parallel resistors.

Summary & Key Takeaways

• Current in parallel resistors splits as it flows through each branch.

• Ohm's law (V=IR) is used to calculate current in each resistor.

• Total current out of the battery equals the sum of currents in each branch.
