Resistor R 1 and Rheostat R h are in parallel, then the parallel resistance is given as. Step 3: Now apply Kirchoff's voltage law to the circuit. The value of the rheostat must be 5 so that heater draws 10 A of current. Solution: Resistance of the rheostat is set to 5 . answered Feb 23, 2015 by Lucy Mentor.

Myostatin (MSTN) is a transforming growth factor-ß family member that plays a critical role in regulating skeletal muscle mass. Genetic studies in multiple species have demonstrated that mutations in the Mstn gene lead to dramatic and widespread increases in muscle mass as a result of a combination of increased fiber numbers and increased fiber sizes.

A Rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption. The construction is very similar to the construction of potentiometer. It uses only two connections, even when 3 terminals (as in a potentiometer) are present. The first connection is made to one end of the ...

Figure 2 Rheostat load control. For example, assume that the load in Figure 2 has a resistance of 10 Ω and the supply voltage is 100 V. If the rheostat is set to 5 Ω, determine the load power, input power and efficiency. If the rheostat in Figure 2 were set to 10 Ω, the load power would be further reduced to 250 W. The efficiency would also ...

Rheostat Applications. Rheostat is generally used in applications where high voltage or current is required such as: Changing the light intensity of a light bulb. An increase in the resistance of the rheostat decreases the flow of electric current, leading to dimming of lights and vice-versa. Generators; Motor speed; Heater and oven …

Both a rheostat and a potentiometer are a type of variable resistor. They feature a similar construction, however, a rheostat features 2 terminals and a potentometer features 3 terminals. A primary difference in functionality is that a rheostat is often implemented to change current, while pots can be used to change the voltage within a circuit.
