# What value of resistor gives the circuit in FIGURE a time constant of

Value of resistor with time constant is .

See the step by step solution

## Step 1: Formula for current decays and equivalent resistance

In a circuit, current decays through an inductor, and the time constant is given by

is the circuit's equivalent resistance

## Step 2: Calculation for resistance value

All values should be substituted,

The two resistors and They are linked in a series.

Simultaneously, the corresponding resistance is equal to
