Electricity Flashcards
Electric power is typically measured in?
Watts
What are the difference between direct current and alternating current?
Alternating current is produced from power stations and sent to our houses. Ac is cheaper to produce
Direct current comes from a direct power source like a car battery.
What is a conductor
a conductor is an object or type of material that allow the flow of electrical current in one or more directions.
What is a insulator
A insulator is a type of material that restricts or stops the flow of electricity or heat.
What is electrical current
Electrical current is the flow of electrons in a current in one second.
What is a series circuit
A series circuit is a circuit in which the electrical current has only one path to take. The current is the same through each resistor BUT the voltage is split
What is a parallel circuit
A parallel circuit has two or more paths for current to flow through. Voltage is the same across each component of the parallel circuit BUT current is the same
What is voltage
an electromotive force or potential difference expressed in volts.
What is ohms
Ohms is a measure of resistance in a circuit.
What is ohms law
Voltage=current*resistance
