Question

Depict a figure showing the arrangement of three resistors of 3 ohm in a circuit to get an effective resistance of (1) 9 ohm (ii) 4 ohm? ​

Answer 1

Explanation:

resistance is 3 ohm

for getting 9 ohm effective 3 Resitor are connected in series

for getting 4 ohms

one Resistor is series with 3 resistors parallel connection
