Answer / miss shendge

mainly the mosfet is a switch. mosfet consist of 3
terminals drain gate &source when gate and source terminal
voltage is 0 that time drain to source current flows very
small but after further increasing gate to source voltage
drain current also increases.

Answer / bhyreshkj

By applying the gate voltage we can create a channel b/w source and drain. thereafter by increasing the Vds, the current Id flow from source to drain. Depending upon gate voltage Vg we can manipulate the width of the channel b/w Source and Drain. it will reflect on Id current variation.
