istivities P, and p2 are connected in parallel across a d.c. battery.
Obtain the expression for the effective resistivity of this
combination
​

Answer 1

Answer:

dont know find from net

Answer 2

Electrical resistance is defined as the process of inhibiting the flow of current across a conductor while conductor is one which initiates the flow of current.

Explanation:

• The expression for the combined resistance which are connected in a parallel combination are:
• R= p*A*l.
• When the resistivity of the parallel combination like p1 and p2 are connected together, the total combination of the resistance will be R= p*A*l (1/p1+1/p2).
• A denotes the area of cross section, L denotes the length of the wire, and R is the combined resistance in a parallel combination.
