Physics formulas

1. Current and potential difference

   • current+charge+time
     • current (A)= charge (C)/ time (s)
       • I=Q/t
   • Potential Difference+energy transferred+charge
     • Potential Difference (V)= energy transferred (J)/ Charge(C)
       • V=W/Q

2. Current-potential difference graphs

   • potential difference+current+ resistance
     • potential difference= current x resistance
       • V=IxR

3. Current, charge, and power

   • Power
     • power=enery transferred/ time
       • P= E/t
     • Power= current x potential difference
       • P= IxV
