Shown in the figure . Find out the current in the wire BD

Text Solution

Verified by Experts

Let at point D potential = 0 and write the potential of other points them current in wire `AD=(10)/(2)=5A` from
A to D current in wire CB `=(20)/(5)=4A` from C to B

`therefore` current in wire BD =1 A from D to B
