Current transfers energy around circuits. Circuit components have various properties that can be measured and then used to make circuits for control and also circuits for testing other components.
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 2 Ω and a 3 Ω resistor in series give what total resistance?
What power is transmitted by 2 A flowing across 5 V?
What power is transmitted by a current of 2 A flowing through a 6 Ω resistor?
