The current enters at A and comes out at D. Some of the resistance are shown. What should be resistance of wire CB so that it draws double of the current that enters the wire BF.

The current enters at A and leaves at F. The values of some resistance are shown. What should be the value of resistance AB so that no current will flow through CB?

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

2 amp current flowing through a wire produces 10 calories ofheat in 20 seconds.What is the resistance of the wire ?

What happens to current and resistance if the voltage is doubled?

What is the cause of resistance offered by the metallic wire in the flow of current through it?

The potential difference between A and B is V. The values of some resistances are shown. The other resistance are equal in values. What should be the value of each of these resistances so that current in circuit is V//3R .
