Which of the following statements are true regarding transformers? Check all that apply. Check all that apply. In a transformer, if the primary coil contains more loops than the secondary coil, then it is a step-up transformer. A transformer is used to increase or decrease an alternating current voltage. A transformer is used to increase or decrease a direct current voltage. A transformer converts mechanical energy into electrical energy. In a transformer, the power input is less than the power output. In a transformer, if the secondary coil contains more loops than the primary coil, then it is a step-up transformer

How do the measurements of charge at the different locations on the sphere compare to each other? the charge measurements are different at all locations on the sphere. the charge measurements are virtually not the same at all locations on the sphere except for the charge at the very top and at the very bottom that are equal. the charge measurements are virtually the same at all locations on the sphere except for the charge at the very top. at the top, the conductive sphere has a small disk that is made of different material. the charge measurements are the same at all locations on the sphere. what happens to the charge on the conductive sphere when it is connected to a source of charge such as the electrostatic voltage source? nothing will happen because no charge goes around the surface of the sphere. the charge on the conductive sphere spreads out over the surface of the sphere; being greater in some specific locations on the sphere. the charge on the conductive sphere spreads out uniformly over the surface of the sphere. the charge on the conductive sphere spreads out non-uniformly over the surface of the sphere.
