Electricity Flashcards
Current equation in words
Current(I)=Voltage(V)÷Resostance
Symbol equation for current
I(current)×V(voltage)
Symbolfor current
I
Symbol for voltage
V
What’s current measured in?
Current is measure in amperes (Amps) (A)
What’s the unit voltage is measured in
Volt
Unit abbreviation for voltage
V
Symbol for voltage
E or V
What the symbol for resistance
R
What’s the unit resistance is measured in
Ohms
What’s the unit abbreviation for ohms
Ω
How to calculate resistance (R) Ω
R=V÷R. Resistance= voltage÷Resistance
What’s a parallel circuit
an electrical circuit that has multiple paths for electricity to flow.
What’s series circuit
A series circuit has all the components in one loop connected by wires, so there is only one route for current to flow
Equation for power
P= I×V power= current×voltage
Equation for energy
Energy=Power×time E=P×Time
What is current?
Current is how much charge is flowing in a current
What is resistance?
Resistance slows down the current
What is potential difference?
Potential difference pushes the current so they can move
What’s another word for Potential difference
Voltage
What’s another word for voltage
