series and parallel circuits

describe the trend in a series circuit for voltage

the total voltage is shared between each component

describe trend in a parallel circuit for voltage

the voltage across each component is the same

what can be said about the resistance if two resistors are in parallel

their total resistance is less than the smallest of the two individual resistances

what can be said about the resistance if two resistors are in series

their total resistance is the sum of the two individual resistances

where is a voltmeter placed in a circuit

in parallel with what is being measured

where is an ammeter placed in a circuit

in series with what is being measured

what is the equation for voltage (if energy and charge are known)

voltage = energy transferred/ charge

what is a volt also known as

joule per coulomb

what is the equation of charge

charge = current * time

describe the current at any point in a closed circuit

the current is the same at all points

what factors does the current in a circuit depend on

voltage and resistance

what is equation of voltage if current and resistance are known

voltage = current * resistance

what happens when current reaches a junction in a circuit

the current is split between two branches
