Investigating the Resistance Of A Light Bulb As The Voltage Is Increased. Plan Resistance is the confrontation of electrons flowing through an electrical component. The resistance slows down the flow through the component, due to the friction created. The current in a circuit gets smaller the bigger the resistance is. To work out resistance you can use this formula: Ohm's Law - R= V (Resistance = Voltage/ Current) I To measure the resistance in a circuit you would need to find out what the voltage and the current is in the circuit. To find the voltage of a light bulb in a series circuit and hence the voltage of the circuit you would need to use a voltmeter, which would be connected in parallel with the light bulb to find the voltage across the bulb. (See diagram below). Then you would need to find the current in the series...
