What are the key differences between series and parallel circuits regarding current?
Series: Current is the same at all points. | Parallel: Total current is the sum of currents in each branch.
What are the key differences between series and parallel circuits regarding voltage?
Series: Voltage drops add up to the battery voltage. | Parallel: Voltage is the same across each branch and equal to the battery's voltage.
How does adding resistors affect total resistance in series vs. parallel circuits?
Series: Adding resistors increases total resistance. | Parallel: Adding resistors decreases total resistance.
Compare the formulas for calculating total resistance in series and parallel circuits.
Series: $R_{total} = R_1 + R_2 + R_3 + ...$ | Parallel: $\frac{1}{R_{total}} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3} + ...$
In a series circuit, what happens to the current if one resistor increases in resistance? What happens in a parallel circuit?
Series: Current decreases. | Parallel: Total current from the source will decrease, but current through other branches remains relatively unchanged if the voltage source is ideal.
What are the key differences between series and parallel circuits regarding current?
Series: Current is the same throughout. | Parallel: Current splits and recombines; total current is the sum of branch currents.
What are the key differences between series and parallel circuits regarding voltage?
Series: Voltage drops add up to the battery voltage. | Parallel: Voltage is the same across each branch.
How does adding resistors affect total resistance in series vs. parallel circuits?
Series: Adding resistors increases total resistance. | Parallel: Adding resistors decreases total resistance.
