Electricity Flashcards
Name the atomic particle that carries the electricity around the electrical circuit.
Electrons carry electrcity around the electrcial circuit.
Name the two types of electrical circuits.
Series circuit and Parallel circuit
Which circuit is better? and why?
Parallel circuits are better because even if one component breaks down, the other part of the circuit will work.
Current is measured in ….
Ampere - Amps
Current can be measured using a …
Ammeter
Voltage is same as …
Potential difference
What drives the electricity around the circuit?
Potential difference (Voltage)
Voltage can be measured using a …
Voltmeter
Potential difference is measured in …
volts
What is a conductor?
A conductor allows the electricity to pass through.
What is an insulator?
An insulator will not allow the electricity to pass through.
What is resistance?
Resistance is a measure of the opposition to current flow in an electrical circuit.
Resistance is measured in …
ohms
In an electrical circuit, does the electricity gets used up?
No, elecricity is never used up, the same amount of electricity will return to the cell.
How does the energy transfer occur in electrical circuits?
From the batteries’ chemical energy store, the electrons carry electrical energy to the bulb and the energy is transferred to light and thermal energy.
