physics -electric circuits cp9 p2 Flashcards
what is a series circuit
two bulbs on the same line
what is a parallel circuit
two bulbs on two different lines
equation for potential difference
OMS =P.D / current or amps
explain resistance
anything which slows the flow of electrons
explain current
a flow of electric charge
explain potential difference
supplied by a cell and pushes the electron around a circuit
what is the charge equation
charge=current x time
what are the current rules in a series circuit
its the same size at every point in the circuit
how do you calculate resistance in a series circuit
add all resistors
what are the P.D rules in a series circuit
share of voltage is dependent on the resistors
what are the current rules in a parallel circuit
current total is adding the current in each loop
what are the P.D rules in a parallel circuit
each loop is equal to eachother
what are the resistance rules in a parallel circuit
half the value of the individual resistors
