Voltage regulators that are adjustable are common, for example the LM338, which can pass up to 5 amps with a suitable heat sink, and the output voltage is set by two external resistors connected to the regulator. A variable resistor can be used to make the output voltage directly adjustable.
What else can I help you with?
Which is better for transmission alternating current and direct current?
Alternating current is better than direct current for transmission.
What is DC in electric stand for?
Volts direct current eg battery As opossd to Vac wich is volts altinating current eg mains supply
Lightning carries Alternating current or Direct Current?
Power lines carry electricity as alternating current.
What is vdi engine?
Variable direct injection system i believe .
Current from a battery is always?
Direct current, as opposed to alternating current.
Flux in DC vary or constant.?
In DC or direct current, the flux is constant. AC or alternating current is variable.
What is a device that can control the current in a circuit?
A variable resistor can be used to control the current in a circuit by adjusting its resistance. By changing the resistance value, the amount of current flowing through the circuit can be regulated.
Is a thermistor direct current?
That depends on the type of thermistor Some solid state thermistors are only able to run on one correct polarity and so are direct current. Other thermistors designed as simple heat variable resistors can run on both direct current and alternating current.
What type of load is LED?
Direct current variable voltage requirements for each application and would be a resistance load.
What is variable DC supply?
Variable DC power supply is: Variable - you can adjust it DC - direct current, electrons (electricity) flows in only one direction power supply - power supply Together, it's an adjustable one-way power supply Hope you find this useful...
Assuming that direct labor is a variable cost product costs under variable costing include only?
B. Direct materials, direct labor, and variable manufacturing overhead.
How do you do a direct variation with an inverse variation problem?
If a variable X is in inverse variation with a variable Y, then it is in direct variation with the variable (1/Y).
Direct labor a variable cost or semi-variable cost?
Direct labor is variable cost as it varies with the change in level of production of units.
Are all direct cost are variable?
Yes generally direct costs are variable costs but there may be some direct costs which can be fixed costs as well.
Relationship between manipulated variable and responding variable?
direct proportion
What is the differences between Fixed Direct labor with variable direct labor?
Direct labor which do not vary with level of production is fixed direct labor while labor vary with change in production is variable direct labor.
Can direct costs display a fixed or variable behavior pattern?
Yes direct cost may be a fixed or variable cost or both.
