10 Transformers are used both to increase the voltage of electricity so that it can travel long distances and to decrease the voltage so that the electricity can be used in your house with relative safety If the voltage across two wires is raised to 2 5 10 V what is its current if 1 0 10 W of power is provided 11 Calculate the amount of power dissipated by this electric heating element if the generator s output voltage is 110 volts and the heater s resistance is 2 5 ohms Now calculate the power dissipated by the same heater if the generator s output voltage is doubled 12 A bulb is plugged into a 120 Volt outlet The Resistance of the bulbs is 330 0 a Calculate the current b Calculate the power c Calculate the work done in 15 seconds 13 A current of 4 5A runs through a lamp with a resistance of 60 ohms in 1 minute What is the work done on the lamp
