Given information

It is required to make a variable timer for intermittent windshield wipers: one

wipe every 15 s, 8 s, 4 s, 2 s, 1 s. The given capacitance is 1µF.

 

Step-by-step explanation

Step 1.

It is known that the product of the resistance R times the capacitance C, which appears in the exponent is called the time constant 𝜏 of the circuit.

Therefore, 𝜏=RC.
