the same
what happens to the voltage across the loads in a series circuit? - ANSWER- it
divides across the resistances
what happens to the current in a series circuit? - ANSWER- It stays the same
everywhere
in a parallel circuit the total resistance of the circuit will always be less than what
resistance? - ANSWER- the smallest resistance
,how do you find the total resistance of a series circuit? - ANSWER- add the
resistances together
how do you find the total resistance of a parallel circuit? - ANSWER- 1/RT = 1/R1
