Updated vocab circuits

circuits actually disgust me.

Voltage

• Measured in volts

• Pressure that pushes the electrons

Current

• Measured in amps

• The electrons flowing through the circuit

Resistance

• Measured in ohms

• The opposite force of electrons

Volts 

• Measures voltage 

• Measured through a voltmeter 

• Represented as V 

• V = IR 

Amps

• Measures current 

• Measured through ammeter  

• Represented as A 

• I = V/R

Ohms 

• Measures resistance 

• Measured through multimeter 

• Represented as an omega sign 

• R = V/I 

Ohm’s Law 

• Linear relationship for most materials  

• V = IR 

• I = v/r 

• R = v/i 

conductor

• The wire 

• Current carrier

load

• The resistor 

• Regulates amount of electrons flowing through  

• Turns electrical energy into other forms of energy

switch

can open and close to stop the flow of electrons

source

gives power to the circuit 

Control 

• it is the switch 

• stop or start the flow of electrons by opening and closing 

electrons

• negative charge  

• moves through the circuit 

Variable Resistance 

• a resistor where the resistance can be changed 

• has a arrow in the middle 

Electric-Hydraulic Analogy 

comparing electrons moving through a circuit like water moving through a hydraulic machine 

ammeter

• measures the amps in the circuit 

• attached near the light because it must pass through to continue the flow of electrons 

Voltmeter 

• measures the volts in a circuit  

• attached parallel to the resistor 

• near the resistor because electrons pass through the easier way without the energy being consumed, meaning the electrons can get measured 

Multimeter 

can measure volts, amps, and resistance 

cell

a single source of energy (single battery) 

Battery 

has multiple cells within it (two or more batteries) 

Static Electricity

• it stays still (in one place) 

• created by a buildup of electrons 

• Opposite attracts, positive to negative 

• same repel, negative and negative repel and vice versa 

Dynamic Electricity 

• moves around  

• steady flow of electrons through a conductor (wire) 

Series Circuit 

• only one path in the circuit for electrons to go through 

• if one light goes out, the rest do too 

Parallel Circuit 

• multiple paths in the circuit for the electron to go through 

• if one light goes out, the rest continue to shine
