calculate the power dissipated by light bulbs and the resistance of the bulbs. Ohms Law relates the current, resistance and voltage: The Power dissipated in a resistor can be derived from Ohm’s Law: The more power a resistor dissipates, the brighter it glows. Therefore, the brighter the bulb, the greater the power rating. Incandescent Bulb Power Consumption Calculator: Enter the capacity of the incandescent bulb, operating hours per day, and the rate per unit and then press the calculate button to get the power consumption of the bulb. By default, you can get the power consumption of 60Watts bulb. Hours Used Per Day: Hr Power Use (Watts): W […]Resistance is measured in ohms _. 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.

In a series circuit you will need to calculate the total resistance of the circuit in order to figure out the amperage. This is done by adding up the individual values of each component in series. In this example we have three resistors. To calculate the total resistance we use the formula: RT = R1 + R2 + R3 Calculate the current through a 60 W lamp rated for 250 V. If the line voltage falls to 200 V, how is the power consumed by the bulb affected? Solution 2: Given, Power, p = 60 w Voltage, v = 250 v As power, P = VI I 250 60 0.24A 2 Resistance of bulb R = V 2502 1041.6 p 60 Now if voltage falls to 200 v, power consumes will be p v2 2002 38.4 W R 1041.6 The resistance in the circuit (resistance in the wires and in the bulbs' filaments) will limit the speed at which the current flows. (This resistance is like the friction in the wheels of the train). However, when the EMF is present to the circuit, all electrons begin moving simultaneously, and thus all the bulbs light up at the same time.
