Practice Questions
Question 1
A circuit consists of two resistors in series: $R_1 = 8 \, \Omega$ and $R_2 = 12 \, \Omega$. If the total voltage supplied is $40 \, \text{V}$, what is the current flowing through the circuit?
Question 2
A parallel circuit consists of two resistors: $R_1 = 6 \, \Omega$ and $R_2 = 3 \, \Omega$. The voltage across the circuit is $18 \, \text{V}$. What is the total current drawn from the voltage source?
Question 3
A resistor in a circuit has a voltage drop of $15 \, \text{V}$ across it, and the current flowing through it is $0.75 \, \text{A}$. What is the resistance of the resistor?
Question 4
A circuit has a total resistance of $24 \, \Omega$ and a current of $0.5 \, \text{A}$. What is the total voltage supplied by the source?
Question 5
A resistor has a resistance of $50 \, \Omega$. If the voltage across the resistor is $100 \, \text{V}$, what is the current flowing through it?
