Sample Questions and Corresponding Answers
Below are representative examples illustrating typical questions in the Gizmo activities and their solutions.
Question 1: Calculating Total Resistance in a Series Circuit
Given: Resistors R1 = 100Ω, R2 = 200Ω, R3 = 300Ω connected in series.
Solution:
Total Resistance, R_total = R1 + R2 + R3 = 100Ω + 200Ω + 300Ω = 600Ω

Question 2: Determining Current in a Parallel Circuit
Given: A voltage supply of 12V, with three resistors R1 = 100Ω, R2 = 200Ω, R3 = 300Ω connected in parallel.
Solution:
- Calculate individual branch currents using I = V/R:
- I1 = 12V / 100Ω = 0.12A
- I2 = 12V / 200Ω = 0.06A
- I3 = 12V / 300Ω = 0.04A
- Total current, I_total = I1 + I2 + I3 = 0.22A

Question 3: Applying Ohm’s Law to Find Voltage Drop
Given: A resistor of 150Ω with a current of 0.2A flowing through it.
Solution:
V = IR = 0.2A × 150Ω = 30V
