Question

you are provided with three resistors of resistance r1,r2,r3, weite the fourmula for the equivalent resistance r​

Answer 1

parallel = 1/R = 1/R1 +1/R2 + 1/R3

series = R = R1+R2+R3

hope you have got the answer

Answer 2

Answer:

Explanation:

The equivalent resistance of a 4-Ω and 12-Ω resistor placed in parallel can be determined using the usual formula for equivalent resistance of parallel branches: 1 / Req = 1 / R1 + 1 / R2 + 1 / R3 ... Now the Ohm's law equation (ΔV = I • R) can be used to determine the total current in the circuit.
