Question

The resultant resistance of two
resistors when connected in series
is 48 ohm. The ratio of resistances
is 3:1. The value of each resistance is​

Answer 1

Step-by-step explanation:

Let one resistor be 3x and other be x. So,

3x + x = 48

or 4x = 48

or x = 48 ÷ 4

or x = 12

So one resistor's resistance is 12 ohm and the other is 3 × 12 = 36ohm

Answer 2

Answer:

36Ω and 12Ω

Step-by-step explanation:

let resistance of each resistor be 3x and x  respectively.

A/Q,

  3x + x = 48Ω

  4x = 48Ω

   x = 12 Ω

resistance of 1st resistor = 3x = 3*12 = 36 ohm

resistance of 2nd resistor = x = 12 ohm
