If load is increased beyond this point, the motor will stall and come to a rapid stop. when one connects two identical capacitors in blank the capacitance will be doubled series parallel a capacitor blank DC and blank AC current through a circuit blocks / passes 4. Most of the digital electronics that you build will use DC. You probably had this as a lesson in high school at some point, but were more interested in other things at the time. Without a rectifier circuit, we could not be able to convert AC to DC. These sine waves indicate voltage and current ? Electrical designers use it to determine how much voltage is required for a certain load, like a motor, a computer, or even a house full of appliances. Also, for a fully resistive circuit, we always have an in-phase voltage and current, so we can find the power consumed at any instant by multiplying the voltage by the current.
