The AC switch and the relay. There is usually a temperature sensor in the passenger compartment ac unit as well.
These cars have something called the Constant Control Relay Module (CCRM), a box mounted under where the battery sits. Inside the CCRM is a relay controlling (I believe) the ground side of the AC compressor circuit. I have had this module fry on 3 different Escorts, with these same symptoms. I'll bet that's the problem here.
Amps Ohm's law states the current is directly proportional to the applied emf (voltage) and inversely proportional to the resistance of the circuit.
Any voltage that is fed into or "applied" to an electrical circuit is referred to as an "applied voltage".
For a series circuit, the applied voltage equals the sum of the voltage drops
this is the amount of voltage a circuit can hold.
When an alternating voltage is applied to a purely resistive circuit, the resulting current is in phase with the voltage.
Current is directly proportional to applied voltage. Ohm's law.
The applied voltage is 53+28 = 81V.
By Kirchhoff's Voltage Law, the sum of the voltage drops around the series circuit will equal the voltage applied to the circuit.
Current is directly proportional to the applied emf (voltage) and inversely proportional to the resistance of the circuit.
The voltage is greater than the applied voltage, why?
As Ohm's law states; Current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
Voltage is equal to the Current multiplied by the Resistance.Without changing the resistance, increasing the applied voltage in a circuit will increase current flow. There is a simple, direct relationship between voltage and current. Double the voltage, twice the current will flow. Triple the voltage, and the current will triple. As voltage (E) equals current (I) times resistance (R), when resistance is fixed, what happens to voltage will happen to current.
