Electricity Flashcards
What is the equation for voltage
Voltage (Volts)= current (Amps) x resistance (ohms)
What are voltmeters connected in?
Parallel
What are ammeters connected in?
Series
Current in a series circuit is?
The same everywhere
Current in a parallel circuit is?
shared between branches
The potential difference in a series circuit
Shared between components1
The potential difference in a parallel circuit
The same across the branches
Resistance in a series circuit is?
The total resistance is the sum of the resistance of each component in the circuit
Resistance in a parallel circuit?
The total resistance of the circuit decreases if you add a second resistor in parallel
What is the equation for charge?
Charge (C) = Current (A) x Time (s)
What is the equation for energy transferred
Energy transferred (Joules) = Charge (coulomb) x Current (amps) x Resistance (ohms)
What is the equation for Power?
Power (W) = Current (A) x Voltage (V)
Another equation for energy transferred?
Energy transferred = current x voltage x time
What is the other equation for voltage?
Voltage (V)/ Potential Difference = Energy (J)/ Charge (Coulombs)
