DC Circuits – A chapter of Electrical Engineering

Q.1 Define DC ?

DC(Direct Current) is the unidirectional flow of current(i.e. flow of electrons) from positive to negative outside the battery and -ve to +ve inside the battery.Its direction and amperage of current does not change. It is used in many household electronics and all devices which uses battery.

Q.2 Define a Network or Circuit ?

Network or Circuit is an electrical…

Introduction: The frequency of operation is represented in KHz then only scalars are used. In networks only scalars are present. Network theory is valid at low frequencies. Only scalars are used. Ohm’s law: Valid only for conductors. At a constant temperature for a source the direction of power will be from negative to positive. All conductors have positive temperature coefficient. It is…
