In the circuit on the bottom, all six resistors share the same value, R. Calculate the equivalent resistance between points A and B when switch S is closed as a percentage of the equivalent resistance when switch S is open.
= _____________ %
If each resistor has a resistance R = 34.3 Ω, calculate the resistance between points A and B after switch S is closed.
= ___________ Ω
Homework Answers
when switch is closed current will not flow from the left bottom loop
so we have to neglect that resistance
=>total resistance = R/3 + R/2 = 5R/6
percentage = (6/5)*(2/3)*100 = 80 %
(2)when switch is closed total resistance = 2R/3 = 2*34.3/3 = 22.86 ohm
