Ohm's Law Calculations: Series and Parallel Circuits Quiz
easy
10 Questions
Question 1 of 10
What is the formula for Ohm's Law?
Ohm's Law states Voltage (V) equals Current (I) multiplied by Resistance (R).
Question 2 of 10
In a series circuit, what is constant?
Current remains the same throughout a series circuit.
Question 3 of 10
In a parallel circuit, what is constant?
Voltage remains the same across all branches in a parallel circuit.
Question 4 of 10
If a 10-ohm resistor has 2 amps flowing through it, what is the voltage across the resistor?
Using Ohm's Law: V = I * R = 2 A * 10 ohms = 20 V.
Question 5 of 10
What happens to the total resistance in a series circuit as you add more resistors?
Total resistance in series is the sum of individual resistances; it increases.
Question 6 of 10
How do you calculate the total resistance of resistors in series?
Resistors in series simply add up: R_total = R1 + R2 + ... + Rn.
Question 7 of 10
How is the total current related to individual branch currents in a parallel circuit?
The total current is the sum of the currents in each parallel branch.
Question 8 of 10
What is the formula to calculate the total resistance of parallel resistors?
The reciprocal of the total resistance equals the sum of the reciprocals of individual resistances.
Question 9 of 10
If three 10-ohm resistors are connected in series, what is the total resistance?
R_total = R1 + R2 + R3 = 10 + 10 + 10 = 30 ohms.
Question 10 of 10
If three 10-ohm resistors are connected in parallel, what is the total resistance?
1/R_total = 1/10 + 1/10 + 1/10 => R_total = 3.33 ohms (approx).
