plus

adv of series

easier and cheaper to build

disadv of series

current cant flow if theres a break in the circuit

adv of parallel

current can flow even if theres a break in the circuit

each component gets the same voltage from the battery

disadv paralell

more difficult and more expensive to build

the greater the resistance, the smaller the ___?

current flow!!!!!

an electric field is created whenever a _____ exists!

charge

the mains voltage is ___V and __Hz

230, 50

in an electric circuit, electrons pass through a ___?

conductor (wire)

what is ohms law

v=ir

what is the electric circuit formula thingy

q=it

how to connect ammeter?

in series

how to connect voltmeter?

in parallel

how to connect an ohmmeter?

directly to a component

what is current

the charge tranferred per unit time

what is voltage

the energy given to each coloumb of charge

what is resistance

an opposition to current flow

what is a series circuit

where all components are connected one after the other

only one path to flow

what is a parallel circuit

there is more than one path (branch) for the current to flow

why are resistors connected in series with LEDs

to protect the led from too high of a current

what does a charged particle experience in an electric field

force

what is the voltage across a resistor directly proportional to

current!! wow

how to test for ohms law?

starting at 0a, increase the current through the resistor in small, even increments by adjusting the voltage on the power supply

then, measure the voltage across the resistor each time by recording the reading on the voltmeter

repeat twice more and take average
