False
Substances that electrical currents can flow through easily are called Insulators.
Substances that electrical currents cannot flow through easily are called conductors.
True
False
Caitlin has an ammeter with three measurement ranges: 0-0.05 A, 0-0.5 A and 0-5 A. She wants to measure a current that is somewhere between 60 mA and 100 mA. Which range is best for her to use?
0-0.05 A
0-0.5 A
0-5 A
None
You have 5 Identical 1.5 V batteries. You have wired all 5 batteries in a series circuit. When you measure the voltage of the circuit you measure 4.5 V. Is this possible?
True
False
The voltage and the current both refer to the way in which a flow of electricity transports energy. (Multiple answers are correct)
The current tells you how much electrical energy each particle is carrying.
The voltage tells you how much electrical energy each particle is carrying.
The current tells you how many of those particles flow past every second.
The voltage tells you how many of those particles flow past every second
3 lights are in a parallel circuit. If one lightbulb breaks, the two other will stop giving light.
True
False
power (W) = voltage
True
False
