Practice Questions

Question 1

In a series circuit with three resistors, $R_1 = 4\Omega$, $R_2 = 5\Omega$, and $R_3 = 11\Omega$, what is the total equivalent resistance of the circuit?

Question 2

A series circuit contains two resistors: $R_1 = 6\Omega$ and $R_2 = 9\Omega$. If the total voltage supplied is $30V$, what is the current flowing through the circuit?

Question 3

In a series circuit, the voltage drop across a $12\Omega$ resistor is $24V$. What is the total current flowing through the circuit?

Question 4

A series circuit has three resistors: $R_1 = 2\Omega$, $R_2 = 3\Omega$, and $R_3 = 5\Omega$. If the total current in the circuit is $1.5A$, what is the voltage drop across $R_3$?

Question 5

In a series circuit with a total voltage of $18V$ and three resistors with resistances $R_1 = 3\Omega$, $R_2 = 3\Omega$, and $R_3 = 6\Omega$, what is the voltage drop across $R_2$?
