current, E R I = The variables, E = 12 V and RT = 80 Ω Substitute variables, 12 V Current in circuits, I = 0.15 A It can be seen quantitatively and intuitively that when the resistance of the circuit is doubled ... current is reduced by half the original value. Next, reduce the RT of the circuit in Figure 12-82 to half of its original value. The effects on the total current are: Figure 12-80. Basic relay. Figure…

Circuit Breakers A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by an overload or short circuit. Its basic function is to detect a fault condition and immediately discontinue electrical flow ... Unlike a fuse that operates once and then has to be replaced, a circuit breaker can be reset to resume normal operation. All resettable circuit breakers should open the circuit in which they are installed regardless of the position…

Determining the Voltage Divider Formula Figure 12-94 shows the example network of four resistors and a voltage source. With a few simple calculations, a formula for determining the voltage divisions in a series circuit can be determined. The voltage ... subscript x is the value of a particular resistor (1, 2, 3, or 4). Using Ohm’s Law, the voltage drop across any resistor can be determined. Figure 12-89. A voltage divider circuit.
