electrical circuits Flashcards
resistance is measured in
ohms
current, voltage, resistance equation:
V = IR
in a series circuit, the current is
the same at all points in the circuit
in a series circuit, the sum of p.d.s across the individual component is equal to
the voltage of the supply
electrons (electric charge) flows from the
negative terminal to the positive terminal
in a parallel circuit, the parallel components are connected directly to
the supply
in a parallel circuit, the sum of the currents in the parallel branches is equal to
the current in the supply
in a parallel circuit, the p.d across each parallel branch is equal to
the supply voltage
in series circuits, the current is the same in all components
connected in series
in series circuits, the p.d across the series part is equal to
the sum of the p.d.s across the individual components
in parallel circuits, the total current in the parallel part equals
the sum of the currents in the parallel branches
in parallel circuits, the p.d across each parallel branch is
the same
