Series and Parallel Circuits Flashcards
In a series circuit, the voltage drops across the entire circuit is equal to the _______ of the voltage drops across the individual resistors
sum
total current in a circuit is the sum of the currents in the separate _______
branches
the total resistance of a ______ circuit is equal to the sum of the individual resistances
series
the voltage across the branches of a _____ circuit is the same everywhere
parallel
in a ______ circuit, the total resistance is less than any single resistance
parallel
the current in a _____ circuit is the same everywhere
series
_____ law may be applied to an entire circuit or to any part of the circuit
Ohm’s
In a ____ circuit, each resistor can be operated independently
parallel
it is not practical for house circuits to be wired in _______
series
a parallel; circuit ____ when too many appliances are placed across the circuit
overloads
a _____ occurs when a piece of low resistance wire is placed across a circuit
short circuit
a _____ is a short piece of metal that melts if a pre-determined current in the line is exceeded
fuse
a _____ is an automatic switch that cuts off the current if the circuit is overloaded
circuit breaker
a ______ must be built with a very high resistance or it changes the circuit it is designed to measure
voltmeter
the resistance of a ____ should be very low so that it does not affect the circuit in which it operates
ammerter
