Static And Charge Flashcards
Protons are
Positively charged
Electrons are
Negatively charged
How do you make static electricity
If you rub two insulators against each other, the electrons will be transferred from one to another. One of the insulators will end up with extra electrons, make it negatively charged, and making it have static electricity. Protons do not get transferred.
What is static charge 0
A property of a body which experiences force in an electric field
What is current, and how do you measure it
Current is the rate at which electrons flow in an electrical circuit, and it’s measured in amperes (A) or “amps”.
Describe how to measure charge,
The current flowing through a component in a circuit is measured using an ammeter. The ammeter can be placed anywhere in the circuit.
What is current measured in
Coulombs
How to calculate charge flow
Charge flow (coulombs / c) = current (Amps / a ) x time (second / s)
What is conventional current
The direction current flows, in the direction of the positive terminal of the battery to the negative terminal.
Small currents are measured in
Milliamperes (mA)
1 mA = 1*10^-3 A
Equation of current
Current = charge / time
Current definition
The rate of flow of charged particles , or charge.
