Resistance is how well something conducts electricity. The lower resistance in a wire the better it will conduct electricity. Copper has a lower resistance than other metals. In order to power a light bulb you need both voltage and current. When you connect fruit in a parallel, it gives you a higher current. Well, the total resistance is 2 ohms plus 3 ohms plus 5 ohms, so it's equal to 10 ohms. So total resistance is equal to 10 ohms. So if I were to ask you what is the current going through this circuit? Well, the total resistance is 10 ohms. We know Ohm's law: voltage is equal to current times resistance. Resistance is how much the circuit resists the flow of the charge. This makes sure the charge does not flow too fast and damage the components. In a circuit, a light bulb can be a resistor. If electrons flow through the light bulb, then the light bulb will light up. If the resistance is high, then the lamp will be dimmer.Leo lucky numbers at wheel world

Solution: We know that, According to Ohm's Law, for a conductor; Relation between current and charge is given by If a bulb needs a big p.d. for a given current then it must have a high resistance. So in series high resistance bulbs are brighter because they have a bigger p.d. across them. In parallel circuits low resistance bulbs are brighter because they have a bigger current through them for the same p.d.Kimmy granger bikes and butt plugs
