Sample Electric Circuit Worksheet Problems and Answers
Below are some sample problems commonly found in electric circuit worksheets, along with detailed solutions.
Problem 1: Simple Series Circuit
Given a series circuit with a 12V battery and two resistors, R1 = 4Ω and R2 = 8Ω, calculate the total resistance, current flowing through the circuit, and the voltage drop across each resistor.
Solution:
1. Total Resistance (R_total):
\[
R_{total} = R1 + R2 = 4Ω + 8Ω = 12Ω
\]
2. Current (I):
Using Ohm's Law: \( I = \frac{V}{R} \)
\[
I = \frac{12V}{12Ω} = 1A
\]
3. Voltage Drop across R1 (V1):
Using Ohm's Law: \( V = IR \)
\[
V1 = I \times R1 = 1A \times 4Ω = 4V
\]
4. Voltage Drop across R2 (V2):
\[
V2 = I \times R2 = 1A \times 8Ω = 8V
\]
Answer Summary:
- Total Resistance: 12Ω
- Current: 1A
- Voltage Drop across R1: 4V
- Voltage Drop across R2: 8V
Problem 2: Parallel Circuit
Consider a parallel circuit with a 24V battery and two resistors, R1 = 6Ω and R2 = 12Ω. Calculate the total current flowing through the circuit and the current through each resistor.
Solution:
1. Total Resistance (R_total):
\[
\frac{1}{R_{total}} = \frac{1}{R1} + \frac{1}{R2} = \frac{1}{6Ω} + \frac{1}{12Ω}
\]
\[
\frac{1}{R_{total}} = \frac{2}{12Ω} + \frac{1}{12Ω} = \frac{3}{12Ω} \Rightarrow R_{total} = 4Ω
\]
2. Total Current (I_total):
Using Ohm's Law:
\[
I_{total} = \frac{V}{R_{total}} = \frac{24V}{4Ω} = 6A
\]
3. Current through R1 (I1):
\[
I1 = \frac{V}{R1} = \frac{24V}{6Ω} = 4A
\]
4. Current through R2 (I2):
\[
I2 = \frac{V}{R2} = \frac{24V}{12Ω} = 2A
\]
Answer Summary:
- Total Current: 6A
- Current through R1: 4A
- Current through R2: 2A
Problem 3: Mixed Circuit
In a circuit with a series and parallel combination, a 10V battery is connected to a resistor R1 = 5Ω in series with a parallel combination of R2 = 10Ω and R3 = 20Ω. Calculate the total current supplied by the battery.
Solution:
1. Calculate R2 and R3 in parallel:
\[
\frac{1}{R_{parallel}} = \frac{1}{R2} + \frac{1}{R3} = \frac{1}{10Ω} + \frac{1}{20Ω}
\]
\[
\frac{1}{R_{parallel}} = \frac{2}{20Ω} + \frac{1}{20Ω} = \frac{3}{20Ω} \Rightarrow R_{parallel} \approx 6.67Ω
\]
2. Total Resistance (R_total):
\[
R_{total} = R1 + R_{parallel} = 5Ω + 6.67Ω \approx 11.67Ω
\]
3. Total Current (I_total):
Using Ohm's Law:
\[
I_{total} = \frac{V}{R_{total}} = \frac{10V}{11.67Ω} \approx 0.857A
\]
Answer Summary:
- Total Current: Approximately 0.857A
