200 point bonus: What unit will your answer be in?
What is current?
How much electric charge flows
200 point bonus: What is its unit
True or false: The equation used to find the generated heat is Q = (I²R)/t, where Q is the heat generated (in joules), I is the current (in amperes), R is the resistance (in ohms), and t is the time (in seconds)
False.
200 point bonus: What is the actual equation?
What feature allows a power bank to adjust output to match the device's needs?
Smart charging or adaptive output
Can you charge a laptop with all power banks? Why or why not?
No, only power banks with high output (e.g., 20V) and USB-C PD
What unit is commonly used to measure the energy capacity of power banks for travel regulations?
Watt-hours or Wh
What is "pass-through charging" and why is it risky with some models?
Charging the power bank while it charges a device; may overheat or damage battery
How does temperature affect a power bank’s performance?
Extreme heat or cold can reduce battery life and efficiency
