Electrical current transfers energy around circuits. The resistance of the circuit has an effect on the size of the current.
What is a flow of charged particles through a conductor called?
What is the unit of electrical charge?
What current flows if 10 C flow past a point in 2 minutes?
What is potential difference also called?
If 25 C of charge transfers 50 J of energy between two points, what is the voltage between those points?
What current flows through a 100 Ω resistor if there is a potential difference of 5 V across it?
A current of 0.5 A flows through a 22 Ω resistor. What is the value of the potential difference across it?
What type of conductor is a fixed resistor?
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?
