Question

Two resistor with resistance 5 ohms and 10 ohms are to be connected to a battery of 6 V so as to obtain: 1) minimum current 2) maximum current...​

Answer 1

Answer:

In Parallel Form

Explanation:

Given:

Two resistors with resistances R1 = 5ohm and R2 = 10ohm, V = 6volt

(a) For minimum current these two should be connected in series. For maximum current these two should be connected in parallel.

(b) In series, Total resistance = 5 + 10 = 15ohms Therefore total current drawn = V/R = 6/15 = 0.4amps

In parallel, Total resistance R is given as 1/R = 1/R1 + 1/R2 1/R =1/5 + 1/10 1/R = 1/10 R = 10/3 ohm Therefore, total current drawn by the circuit = V/R = 6/(10/3) = 1.8amps.
