easy
10 Questions
Question 1 of 10
What is the total resistance of three resistors (10?, 20?, and 30?) connected in series?
In series, resistances add directly: R_total = R1 + R2 + R3.
Question 2 of 10
In a series circuit, what is constant across all components?
Current flows through each component in the same path.
Question 3 of 10
What is the total resistance of two 100? resistors connected in parallel?
For equal parallel resistors: R_total = R/n, where n is number of resistors.
Question 4 of 10
In a parallel circuit, what is constant across all components?
Each component has the same voltage drop across it.
Question 5 of 10
If a 12V battery is connected to a 4? resistor, what is the current flowing through the resistor?
Ohm's Law: I = V/R, therefore I = 12V/4? = 3A.
Question 6 of 10
Two resistors (2? and 4?) are connected in series and powered by a 12V source. What is the current?
R_total = 2? + 4? = 6?, I = V/R, I = 12V/6? = 2A.
Question 7 of 10
What is the formula for calculating total resistance in a series circuit?
In series, resistances add directly.
Question 8 of 10
What is the formula for calculating total resistance in a parallel circuit?
The reciprocal of the total resistance is the sum of the reciprocals of individual resistances.
Question 9 of 10
A 10? and a 30? resistor are connected in parallel. What is their total resistance?
1/R_total = 1/10 + 1/30; R_total = 7.5?.
Question 10 of 10
If a circuit has a voltage of 24V and a current of 2A, what is the total resistance?
Ohm's Law: R = V/I, therefore R = 24V/2A = 12?.
