Def : the energy or pushing force available to move electrons through a circuitUnit: volt (V)Symbol: VMeasured using an instrument called a voltmeter
-
= 1.5 volts3.0V?VIf
-
Def: difference between the charges at the beginning of a circuit and at the endCharges flow because of potential difference.
-
3.0 V0.0 V3.0 VBy the time a charge travels through a circuit it will essentially have lost its voltage or push
-
Def: how much the voltage decreases as it passes through each resistor on the way back to the negative end of the battery
The more light bulbs you have in a series circuit, the dimmer they are because they have to share voltage
-
Resistance is the tendency for materials to oppose the flow of electricity
Symbol: (R) Unit: ohm () Measured by an ohmmeterHigh resistance = insulators.Low resistance = conductors.
Anything using electricity is a resistor!!
-
Your TurnFind the voltage drop across the missing bulbs405
-
In a parallel circuit, the voltage drop across EACH resistor is equal to the total voltageLight bulbs wired in parallel have the same brightness!
-
Def : the rate of FLOW of electrons through a wireUnit: Amperes (amp)Symbol: IIt is measured using an ammeter
-
Current in a series circuit is the same for each resistor (light bulb).
-
Current is divided up between each path; Each path gets the necessary number of amps.
-
TYPES of CURRENTDirect Current (DC) flows in one directionEx. - BatteriesAlternating Current (AC) reverses back and forthEx. Household current

to Electrical CurrentWhich of the following do you think would be most resistant to electrical current?PlasticInsulatorConductorOR
-
Resistance is affected byLengthThe longer the wire, the greater the resistanceDiameterThe smaller the diameter, greater the resistanceMaterialPoor conductors have high resistanceTemperatureThe hotter the wire, the greater the resistance
