A 4.70 kilo ohm's resistor is in parallel with a 2.32 kilo ohm's resistor. if a current of 689 micro ampere flows through the larger resistor. what is the rate at which the smaller resistor produces heat?

Homework Answers

Answer #1

Let the rate of heat produced by a smaller resistor is H.

Let the current passes through the smaller resistor, is IS.

We know for a parallel circuit

  

  

Now the rate of the heat produced by the small resistor is

  

  

  

The rate at which the smaller resistor produces heat is 0.7739731298 cal/s or 0.774 cal/s approximately.
