Electricity Flashcards
What is the charge on a proton
Positive
What is the charge of an electron
Negative
What is the charge on a Neutron

What is the unit used to measure electric current?
Ampere
What is the instrument used to measure electric current?
Ammeter
What is the unit used to measure voltage?
Volt
What is the instrument used to measure voltage?
Voltmeters
What units is resistance measured?
OHM
What is the difference between series and parallel circuits?
Parallel- the voltage across each of the components is the same, and the total current is the sum of the currents flowing through each component
Series- every device must function for the circuit to be complete. If one bulb burns out in a series circuit, the entire circuit is broken
Why are electrical wires wrapped in insulating plastic?
To protect people from electrical shock.
To protect the copper wire from installations
and to reduce heat loss
