Charge (a)

Notes

Charge (a) Measures in Coulombs (c) Current = Time taken divides by Carge Time taken = (T) Curent (I) is Measured in Amps (A) Measures with an Ameter Charge = Curent X time Voltage or p.d potential difference = Voltage (V) Voltage is measured with a volt meter The volt meter is put parallel to the device ( Bulb) Th voltage or p.d is the same as going up to going down Series V total= V1 + V2 If its prallel Vspply = V1 = V2 Of the current is in series its all the same but if it is paralel is a1 equal to a2 plus a3 Bulb The resistance in the bulb changes The resistance of the bulb increases as the temperature increases the current decreases Led or diode
