Series and Parallel Circuit Analysis Techniques…

Q: In a series circuit, what is constant across all components?

Current — Current remains the same in all parts of a series circuit.

Q: In a parallel circuit, what is constant across all components?

Voltage — Voltage is the same across all branches in a parallel circuit.

Q: How is total resistance calculated in a series circuit?

R1 + R2 + R3 + ... — Total resistance is the sum of individual resistances in series.

Q: How is total resistance calculated in a parallel circuit?

1/(1/R1 + 1/R2 + 1/R3 + ...) — Total resistance is calculated using the reciprocal of the sum of reciprocals.

Q: What happens to the current in a series circuit if one component fails open?

Current goes to zero — An open circuit breaks the path, thus current stops flowing.

Q: What happens to the current in a parallel circuit if one component fails open?

Current remains the same in the other branches — Other branches are unaffected; only current through the open branch is zero.

Q: If two 10-ohm resistors are connected in series, what is the total resistance?

20 ohms — R_total = R1 + R2 = 10 + 10 = 20 ohms

Q: If two 10-ohm resistors are connected in parallel, what is the total resistance?

5 ohms — R_total = 1 / (1/10 + 1/10) = 5 ohms

Q: Ohm's Law states the relationship between voltage (V), current (I), and resistance (R). Which equation correctly represents this law?

V = I * R — Ohm's Law states V = I * R

Q: In a series circuit with two resistors, if the voltage across the first resistor is 5V and the second resistor is 10V, what is the total voltage?

15V — Total voltage is the sum of individual voltage drops in a series circuit.
