Chapter 64, Problem 1RQ
To determine
The diagram for the schematic symbol for the TRIAC.
Expert Solution & Answer
Explanation of Solution
The TRIAC is the device that is used to control the AC power and they can swtich the high voltage and the large current over the both the cycle of the AC power. The TRIAC is also a three terminal bidirectional device.
Consider that the PNPN junction is connected in parallel to the NPNP junction is called the TRIAC.
The schematic symbol for the TRIAC is shown in Figure below.
The symbol for triac is shown in Figure 1

Problem 9.5
9.5 A 1080-kg car is parked on a sloped street. The figure shows its wheels and the position of
its center of mass. The street is icy, and as a result the coefficient of static friction between
the car's tires and the street surface is μs = 0.2. Determine the steepest slope (in degrees
relative to the horizontal) at which the car could remain in equilibrium if
a. the brakes are applied to both its front and rear wheels;
b. the brakes are applied to the front (lower) wheels only.
