the effective resistance between a and b is
Answers
The effective resistance between a and b is 10 ohm.
Given - Two resistances
Find - Effective resistance
Solution - As per the placement of resistors in wire, the current from 4 ohm resistor will move forward towards B point. If the resistor would have been placed opposite to 6 ohm, the two resistors would have been connected in parallel. Accordingly effective resistance would have been calculated. This effective resistance would have been added with 4 ohm to find overall effective resistance between a and b.
In absence of any other resistor, the 4 ohm resistor and 6 ohm resistor will be considered in series. Thus, to calculate effective resistance, we will simply add the two resistances.
Effective Resistance = 4 + 6
Effective resistance = 10 ohm
Hence, the effective resistance is 10 ohm.
