equations

• charge= current x time (Q=IT)
• Voltage = current x resistance ( V=IR)
• Resistance in series= R1+R2+R3…
• Resistors in parallel= 1/R1 + 1/R2 ….
• power = current x current x resistance (P = I^2R)
• power = current x voltage
• power= work done/time taken to do work (Joules/s)
• work done = charge x voltage
