Current (I) = 2 amperes

Resistance (R) = 960 ohms

To Find:

Current (I) when the resistance (R) is unknown.

Formula:

I = k/R

where,

k is a constant.

Finding the constant (k):

Substitute the given values in the formula:

2 = k/960

k = 2 * 960

k = 1920

Determining the current for the unknown resistance:

Substitute the value of k in the formula:

I = 1920/R

Therefore, the current (I) is directly proportional to the reciprocal of resistance (R).
