What are the key differences between series and parallel circuits?

Series: Single path for current, current is the same through all components, voltage is shared. Parallel: Multiple paths for current, voltage is the same across all branches, current is divided.

What are the key differences between series and parallel circuits?

Series: Single path for current, current is the same through all components, voltage is shared. Parallel: Multiple paths for current, voltage is the same across all branches, current is divided.

What happens to the current in a series circuit if the resistance is increased?

The current decreases, according to Ohm's Law ( $V=IR$ ).

What happens to the total current from a voltage source in a parallel circuit if one resistor is removed?

The total current decreases because the total resistance increases.

What happens when the switch is open in a circuit?

The circuit is broken, and no current can flow.

What are the steps to applying Kirchhoff's Loop Rule?

Draw the circuit. 2. Choose a loop. 3. Assign currents. 4. Follow the loop, noting voltage gains (+) and drops (-). 5. Set up the equation: Sum the voltages and set equal to zero. 6. Solve for unknowns.
