Resistance is an opposition, to the flow of charge in a circuit, The symbol for a resistor is, Voltmeters measure, potential difference, Ammeters measure, current, The symbol for a voltmeter is, The symbol for an ammeter is, The longer the piece of wire, the higher the resistance, The wider the piece of wire, the lower the resistance, Resistance is, directly proportional to the length of a wire, For a fixed resistor, the potential difference is directly proportional to the current, IV graph for a fixed resistor, IV graph for a filament bulb, IV graph for a diode, Ammeters are connected, in series, Voltmeters are connected, in parallel
