P3.9 Energy & Power Formulas

• What is the formula that links energy, power, and time?


  Energy (E)= Power (P) x Time (t)

  E= PT
• What is the formula that links current, energy, time, and voltage?


  Energy (E)= Voltage (V) x Current (I) x Time (T)

  E= VIt
• What is the formula that links charge, energy, and voltage?


  Energy (E) = Charge (Q) x Voltage (V)

  E= QV
• What is the formula that links current, power, and voltage?


  Power (P)= Current (I) x Voltage (V)

  P= IV
• What is the formula that links current, power, and resistance?


  Power (P)= Current $\left(I\right)^2$ x Resistance (R)

  P= $I^2$R
