What resistor is need pull 1500Ma?
To calculate the resistor needed to pull 1500 mA (1.5 A), you need to know the voltage across the resistor. Using Ohm's Law (V = I × R), you can rearrange it to find R (Resistance = Voltage / Current). For example, if the voltage is 5V, the resistor needed would be R = 5V / 1.5A = 3.33 ohms. However, ensure the resistor can handle the power dissipation, calculated as P = I² × R, which in this case would be approximately 7.5 watts.
Why are the slip rings needed in dc motor?
Slip rings are needed to connect a rotating armature to external fixed circuits.
What value of resistor will be needed to produce the current of 100mA when a voltage of 12V is applied across the resistor?
R = E/I = (12)/(0.1) = 120 ohms(Make it a big one. It dissipates I2R = 0.01 x 120 = 1.2 watts.)
How much current is needed to produce 50 mA of current through a 240Ω resistor?
To determine the voltage needed to produce 50 mA (0.05 A) of current through a 240Ω resistor, you can use Ohm's Law, which states ( V = I \times R ). Plugging in the values, ( V = 0.05 , \text{A} \times 240 , \Omega = 12 , \text{V} ). Therefore, a voltage of 12 volts is required to produce a current of 50 mA through a 240Ω resistor.
How is the stepped resistor differ from the fixed resistor?
A stepped resistor, also known as a variable resistor or rheostat, allows for adjustable resistance levels, enabling fine-tuning of current flow in a circuit. In contrast, a fixed resistor has a constant resistance value and does not change. While stepped resistors can be used for applications requiring variable resistance, fixed resistors are typically used in applications where a specific resistance is needed. The ability to adjust resistance in stepped resistors offers greater flexibility in circuit design.
Materials needed to make a resistor.?
carbon
If you have a 12point6V battery and a 9V receiver how can you work out which resistor is needed?
you better not. you need a 9V regulator for this, not a resistor!
Why HLT instruction is not needed for microcontrollers?
There should be some process to stop the execution of a program.In microcontroller it is done by jumping to same location.
How is the microcontroller used for the traffic light control application?
In a traffic light control application, a microcontroller is used to manage the timing and sequence of the traffic lights at an intersection. It processes input from sensors or timers to determine when to change the lights, ensuring safe and efficient traffic flow. The microcontroller executes programmed logic to switch the lights from red to green to yellow, while also coordinating pedestrian signals if needed. By implementing these functions, the microcontroller enhances road safety and optimizes traffic management.
Is flywheel needed for external combustion engine?
no

What does fuel pump resistor do?
A fuel pump resistor runs the fuel pump at a lower speed when the demand for fuel is lower. When more fuel is needed the system bypasses the resistor and allows the fuel pump to run at full speed.
Can you operate dc motor using computer via microcontroller?
Yes. You probably don't want to do so directly unless it's a really small motor. An H-bridge, or similar circuit is probably easiest to use. The microcrontroller would interface with the computer, likely through a serial link. The microcontroller would then control the H bridge through several outputs. Depending on the microcontroller, H-bridge design, and motor to be controlled, the microcontroller might not be able to drive the H-bridge and an intermediate driver chip may be needed.
Why ULN2803 is not directly connected to a relay why it is connected to a relay via microcontroller?
You actually have that reversed. A microcontroller is connected to a relay via a ULN2803 (or other power device driver IC) because the output pins of the microcontroller can't drive relays. The ULN2803 darlington transistors provide the power amplification and the inductive kickback protection needed to drive the relay while only lightly loading the microprocessor output pins.
What size resistor needed to fool o2 sensor?
It doesn't work that way. An oxygen sensor can not be bypassed.
What size resistor is needed to drop 24 volts dc to 12volts dc?
Its dependent what will by rated power of the device (current).
In animals which condition is needed for external fertilization?
a moist environment
