if resistance R1 and R2 are connected in parallel combination ,then write formula for effective resistance of parallel combination |
|
Answer» tion:Two ways:1.R = (R1 x R2) / (R1 + R2)2.R = 1 / (1/R1 + 1/R2)On a CALCULATOR: input R1, press 1/x, then press +, input R2, press 1/x, press =, then 1/x.If you have more RESISTORS of VARIOUS values in parallel, just continue inputting their values and PRESSING 1/x after each, and press = when you got all of them, and then 1/x. Very simple, and fairly FAST. |
