Question

There are a variaty of sansors which work on the basis of changing reaistance due to an external influance. For example, forca-sansitive resistors (FSR) will change thair resistance when a force is a exertad (when you squesze them). Computers are good at reading out voltages so these devices aro o en com bined th a mod value resistor to create a voltage di der circuit. Consider the circuit shown below whero the xed resstor, R has ? resistance of 10.0 80.0 k? when thera i no force acting on the FSR. A voltaga V=?.00 V is being appliad to the two serie; rasistors. 2 and the FSR has a res stance? FSR What is the current flowing through the FSR when there is no force being applied to the F5R? 5.56x10- A ou are correct. r receipt no. is 156-1550 Previous Tries What is the current lowing through the foxed resistor when there is 5.56x105 A no force being epplied to the FSR? Previous Trias r receipt no. is 156-9258 Consider the negative terminal of the voltage source to be at a potential of zero Volts. What is the electric potential (voltoge) at the location A between the two resistors? 0.556 V ou are correct. r recaipt no. is 156-42sPrevius Tries Suppose thst if a 1.20 N is applied to the FSR, its resitance decresses to 6.00 k2. What would be the new current through the fixed resistor, R? Submit Answar Tries 2/10 Previaus Trica electric potential at Location A between the two resistors with the applied force of 1.20 N? Submit Answer Tries 010

Explanation / Answer

D)

equivalent resistance

Req=10+6 =16 Kohms

Current flowing through fixed resistor R is

I=5/16*103= 3.125*10-4 A

e)

VA=3.125*10-4*10*103 =3.125 Volts
