Electrical current transfers energy around circuits. There are two types of current: direct and alternating.
What is a flow of charged particles called?
What unit is charge measured in?
What current flows if 10 C flow past a point in 2 minutes?
What is potential difference also called?
If 25 C of charge shifts 50 J of energy between two points, what is the voltage between those points?
What current flows in a 100 Ω resistor if 5 V is connected across it?
What type of conductor is a fixed resistor?
A 5 Ω and a 3 Ω resistor in series give what total resistance?
If resistors are placed in parallel, their equivalent resistance is:
Bigger than either resistor
The sum of the two resistors
Smaller than either resistor
What happens to the resistance of an LDR placed in bright light?
