The 5 Ohm resistor will have more current passing through it than the 10 ohm resistor. Since the resistors are in parallel the Voltage across each resistor is the same.

Power or the amount of heat in terms of the question can be derived from Power = Voltage * Current.

Ohm's law tells us that the current flowing through a resistor is equal to the Voltage across the resistor divided by the resistance. The formula for power is then the Voltage * Voltage / Resistance.

Since V^2 / 10 is smaller than V^2 / 5 we know that the 5 ohm resistor will always have more power dissipated than the 10 ohm resistor.

True, dawg.

The voltage adds if you connect in series (positive to negative). It stays the same if in parallel (Positive to Positive and Negative to Negative).

Let t=0 denote the start of transmission. At t=1 msec, the first frame has been fully

transmitted. At t=271 msec, the first frame has fully arrived. At t=272 msec, the frame

acknowledging the first one has been fully sent. At t=542 msec, the acknowledementbearing frame has fully arrived. Thus, the cycle is 542 msec. A total of k frames are sent

in 542 msec, for an efficiency of k/542. Hence

a) k=1, efficiency=1/542=0,18%

b) k=7, efficiency=7/542=1,29%

c) k=4, efficiency=4/542=0,74%

That depends on the gain of the transmitting and receiving antennas, and also on the
sensitivity of the receiver.

So there are two reasons why the question can't be answered here:

1). There's not enough information given to arrive at a unique answer.

2). I make my living designing exactly these situations. WikiAnswers is a lot of fun,
but I'm not about to drop a freebie.

It all depends on the hardware you are given. Traditionally it would be Assembly because of its low requirements and size after build or Ansi-C compiling down to assembly. However now with Hardware JVM's coming out Java has also became an option as well as theoretically any language that runs on the JVM(Scala, ruby...).

a transistor can only work in active region cox in active region collector base junction is in reverse bias and emitter base junction is in forward bias.

Watt's law is discovered Save by lance adrian of consuelo...

He discover it by the help of his bestfriends , but they are not actually his bestfriends..

Sure. If you want sound when the circuit is energized, use a buzzer.

If you want a visual indication when the circuit is energized, use an LED.

dc motors generate more noise.

Any controller used in motors or electrical drives are only to get variable speed or variable torque or to get higher efficiency.

The controller can be anything, it might be micro controller or it can be DSP controller or may be other.

But DSP controller finds some advantages over micro controller.

Both the controllers are Digital controllers only, but DSP controller has inbuilt Analog to Digital converter, inbuilt Digital to analog converter , inbuilt counter and inbuilt pulse generator.

With a micro controller we need to assemble all the above converters, counters and pulse generators externally, so DSP based electrical drives are more popular though the cost is more compared to micro controllers.

If you're looking for a job in the HVAC industry, the best one I've found has been HVACAgent.com They've found me several really good jobs.

a digital countdown timer is simply a digital synchronous counter consisting

of registers and flip flops

example :to count the number from 0 to 15 we require a four bit synchronous counter

which will pass to sixteen stages continuously with shifting from one stage to other after every clock pulse and the cycle continues

the most basic transformers have at least two coils, a primary and a secondary. A transformers nameplate will provide you with the max allowed voltage and current, as well as a voltage per turn ratio. for example a step down transformer could have a primary of 120 volts and a secondary of 24 volts this would give you a ratio of 5:1.

A 600 mAh battery can produce 75 mA for about 8 hours. If it is called upon to deliver 600 mA, it will last somewhat less than one hour.

This is because ampere-hour ratings for batteries are, by standard agreement, normalized to an eight-hour rate. The actual rating is only a comparative rating, so you could properly say that a 900 mAh battery, for instance, will last 1.5 times longer than a 600 mAh battery.

Kirchoff's voltage law states that the signed sums of the voltage drops in a series circuit add up to zero.

Kirchoff's current law states that the current everywhere in a series circuit is the same, more specifically, that the signed sums of the currents entering a node is zero.

The dropper diode voltage regulator is a type of voltage regulator. It is comprised of a single diode that serves as the voltage regulating device.

Yes, voltage effects the output of electric heaters. The wattage output rating of the heater will not be reached due to the lower applied voltage. For example if the heater is 5000 watts at 277 volts, the current is I = W/E 5000/277 = 18 amps. The resistance of the heater is R = W/I (squared) = 5000/18 x 18 (324) = 15.43 ohms. Applying 220 volts on the same heater whose resistance is 15.43 ohms results in this new heater wattage rating. W = E (squared)/R = 220 x 220 (48400)/15.43 = 3137 watts.

W = watts, I = amperage, R = resistance in ohms and E = voltage.

TVs receiving broadcast programming do, they just use it to produce both picture and sound; instead of just sound as an ordinary radio does.

TVs receiving cable programming don't.

TVs receiving satellite programming do, but the radio waves are in the microwave band transmitted from the satellite and received by your dish, where they are down converted via a microwave superheterodyne stage in the dish so that they are in the frequency range the TV can handle.
