What is the equation that link charge, current and time?
Charge = current/time (Q = I/t)
Charge = current x time (Q = I x t)
Current = charge x time (I = Q x t)
Time = charge x current (t = Q x I)
What is the equation that links potential difference, current and resistance?
potential difference = current x resistance (V = I x R)
potential difference = current/resistance (V = I/R)
current = potential difference x resistance (I = V x R)
Resistance = current / potential difference (R = I/V)
What is the equation that links power, current and potential difference?
Current = power x potential difference (I = P x V)
Potential difference = current/power (V = I/P)
Power = current x potential difference (P = I x V)
Current = potential difference / power (I = V/P)
What is the equation that links Power, Current and Resistance?
Power = current x resistance (P = I x R)
Power = current2 x resistance (P = I2 x R)
Power = current x resistance2 (P = I x R2)
Power = current2/resistance (P = I2/R)
What is the equation that links Power, Energy and Time?
Power = energy x time (P = E x t)
energy = power x time (E = P x t)
Time = power x energy (t = P x E)
energy = power/time (E = P/t)
What is the equation that links Energy, Charge, and Potential Difference?
Energy = charge/potential difference (E = Q/V)
Energy = potential difference / charge (E = V/Q)
Energy = charge2 x potential difference (E = Q2 x V)
Energy = charge x potential difference (E = Q x V)
What is the equation that links kinetic energy, mass and velocity?
Kinetic Energy = mass x velocity (KE = m x v)
Kinetic Energy = 0.5 x mass x velocity (KE = 0.5 x m x v)
Kinetic Energy = 0.5 x mass x velocity 2 (KE = 0.5 x m x v2)
Kinetic Energy = 0.5 x mass2 x velocity (KE = 0.5 x m2 x v)
What is the equation that links gravitational potential energy, mass, gravitational field strength, and height?
Gravitational Potential = mass x height x gravitational field strength (GPE = m x h x g)
Gravitational Potential = mass x (height/gravitational field strength) (GPE = mx(h/g))
Gravitational Potential = mass/(height x gravitational field strength) (GPE = m/(hxg))
Gravitational Potential = mass x gravitational field strength/height (GPE = mx(g/h))
What is the equation that links power, work done and time?
Power = work done x time (P = W x t)
Power = work done/time (P = W/t)
Power = time/work done (P = t/W)
Power = work done x time2
What is the equation that links work done, force and distance?
Work Done = force/distance (W = F/d)
Work Done = distance/force (W = d/F)
Work Done = force x distance (W = F x d)
Work Done = force x distance2 (W = F x d2)
