GIZMOS STUDENT EXPLORATION
CERTIFICATION EVALUATION 2026 SOLVED
QUESTIONS
◉ Is the current the same throughout, or does it change? Answer:
The same
◉ What is the current in the wire now? Answer: 2.7 amp
◉ What is the mathematical relationship between voltage (V),
resistance (R), and current (I)? Answer: V= IxR
◉ Apply: The light bulb is also a resistor. Place the light bulb in the
circuit, then use Ohm's law to find the resistance of the light bulb.
What is it? Answer: I=V/R
◉ Observe: Turn the light switch ON and observe the light bulb.
Then start replacing the wire segments with new light bulbs.
How does each new light bulb affect the others? Answer: It takes up
electricity which causes the other bulbs to dim.
