A positive camber is good for keeping a recreational vehicle stable, while the negative camber is better for allowing high performance vehicles to have a better ability to turn corners faster and accurately. The toe angle affects directional control, turning response and tire tread life. Toe-related tread wear will cause a "feathering" wear pattern across the tread. If too much toe-in is present, the feathering will angle toward the center of the vehicle. Increasing the amount of positive caster will increase steering effort and straight line tracking, as well as improve high speed stability and cornering effectiveness. Positive caster also increases tire lean when cornering (almost like having more negative camber) as the steering angle is increased.
Shane's 100-watt radio draws 7 amps of current on a 120-volt circuit. What is the resistance in the radio?
Answer:
Resistance, R = 2.04 Ohms.
Explanation:
Given the following data;
Current = 7 amps
Circuit voltage = 120 Volts
Power = 100 Watts
To find the resistance;
First of all, we would calculate the potential difference (voltage level) used by the radio.
Power = current * voltage
100 = 7 * voltage
Voltage = 100/7
Voltage = 14.29 Volts
Next, we solve for the resistance of the radio;
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
[tex] V = IR[/tex]
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
Substituting into the formula, we have;
[tex] 14.29 = 7*R[/tex]
[tex] R = \frac {14.29}{7} [/tex]
Resistance, R = 2.04 Ohms.
