Values And Equations Flashcards
What is charge?
Charge is the value of electricity flowing in a circuit.
What is current?
Current is the flow of electrons.
What is potential difference?
Potential difference is what pushes the current around.
What is resistance?
Anything that slows down the current.
What is the equation linking charge, current and time?
Charge (Q) = Current (I) × Time (t)
Charge is measured in coulombs.
Current is measured in amps.
Time is measured in seconds.
What is the equation linking potential difference, current and resistance?
Potential difference (V) = Current (I) × Resistance (R).
Potential difference is measured in volts.
Current is measured in amps.
Resistance is measured in ohms.
What is the equation linking power, potential difference, and current?
Power (P) = Potential difference (V) × Current (I).
Power is measured in Watts (W).
Potential difference is measured in Volts (V).
Current is measured in amps (a).
What is the equation linking Power, Current, and Resistance?
P = I² × R.
What is the equation linking Power, Energy, and Time?
Energy (J) = Power (W) × Time (s).
E = P × t.
What is the equation linking Energy, Charge, and Potential difference?
Energy (J) = Charge (c) × Potential difference (V).
E = Q × V.
