Question

A wire offers resistance of a 5ohm/m. 3 pieces of 3m, of this wire are connected in

parallel,find the equivalent resistance of the combination. A battery provides a current of 1A

each in all 3 wires, if the internal resistance of the battery is zero, what is the E.M.F of the

battery​

Answer 1

Answer:

Given: R1 = 2 ohm, R2 = 3 ohm, R3 = 6 ohmFormula: 1/R = 1/R1 + 1/R2 + 1/R3 = 1/2 + 1/3 + 1/6 R = 3 + 2 + 1/6 = 6/6 = 1 ohm.
