Question

Three resistance x1, x2 and x3 are connected in a circuit in different ways, x is the effective

resistance. The properties observed for these different ways of connecting x1, x2 and x3 are

given below. Write the way in which they are connected in each case. (I – current, V –

potential difference, x – effective resistance)

i. Current I flows through x1, x2 and x3

ii. x is smaller than x1, x2 and x3

iii. The potential difference across x1, x2 and x3 is the same.​

Answer 1

Explanation:

x = x₁ + x₂ + x₃: The resistances must be in series connection because this is the expression to calculate effective resistance in series connection. f. x = 1/ 1/x₁+1/x₂+1/x₃: The resistances must be in parallel connection because this is the expression to calculate effective resistance in series connection
