Question ➲

Calculate resistance between point A and B for the given ladder of infinite resistance.


Figure in attachment..

Answer 1

Answer:

• Let the equivalent resistance between a and b be R.As the ladder is inifinite, R is also the equivalent resistence of the ladder ro the right of the points c and d. Thus,we can replace the part to the right of cd by a resistances R and redraw the circuit as in figure. or,`R=r+sqrt(r^(2)+4r^(2))/2=(1+sqrt5)/2r

Answer 2

total resistance of circuit will be 13 OhM

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.
