Practice Questions

Question 1

A series RC circuit is connected to a DC voltage source. If the voltage across the resistor ($V_R$) is $8 \text{ V}$ and the voltage across the capacitor ($V_C$) is $6 \text{ V}$, what is the total voltage of the source ($V_S$)?

Question 2

In an AC circuit, what is the phase relationship between the voltage across an inductor ($V_L$) and the current ($I_L$) flowing through it?

Question 3

An AC circuit contains a resistor of $R = 5 \, \Omega$ and an inductor with an inductive reactance of $X_L = 12 \, \Omega$ connected in series. What is the impedance ($Z$) of the circuit?

Question 4

A parallel DC circuit has two resistors, $R_1 = 10 \, \Omega$ and $R_2 = 15 \, \Omega$, connected across a $30 \text{ V}$ source. What is the total current drawn from the source?

Question 5
