Draw a circuit diagram of a dry cell connected to a bulb through a switch.Mark the positive and negetive terminals of the cell and also show the direction of flow of current.And explain the flow of current

Dear Student
Refer the figure given below :

The electron always flow from negative termnal to positive terminal of the battery.
In convention it is assumed that proton flow from Positive to nagative(but actual proton not flows). In clinical convention direction of flow of positive charge (proton)is taken as the direction of current
