The ____ of a battery is the amount of energy it gives to each coulomb of charge. A voltmeter can be connected across the ____ of a battery. This will give a reading for the ____ (p.d), measured in ____. If the p.d across a cell is 1 volt, then 1 ____ of potential energy is given to each ____ of charge. In other words, 1 volt means 1 ____ (J/C). Two resistors in series will have a ____ resistance than either on its own. Two resistors in parallel will have a ____ resistance than either on its own. When the temperature is higher, the resistance of the wire will be affected, causing the current flow to be ____ thus the bulb will be ____.
