Question

Find the net resistance between points a and point b in the diagram shown.
If a voltage 6v is applied across ab, find the amount of current in the circuit

Answer 1

Explanation:

7onm and 3ohm are in series net resistance 10 ohm

this 10ohm resistance is parallel to 10ohm resistance of BD

net resistance =10*10/10+10=5ohm

this 5 ohm resistance is in series with 5ohm resistance of AD

net resistance become 10 ohm

this 10ohm resistance is parallel to 10 ohm resistance of AB

net resistance =10*10/10+10=5ohm

net resistance between A and B is 5ohm

current =6/5=1.2 amp
