Question

b) 10 V battery is connected in a electric circuit. Between A and B points 20ohm
and 30ohm resistors connected to get least resistance in the circuit. Find the
resultant resistance between A and B and find the current in the circuit.​

Answer 1

to get least resistance ,resistors should be connected in parallel .

therefore , resistance in the circuit is 1/20 +1/30= 1/12

resistance = 12 ohm

v=ir

10/12 = I

current = 10/12
