Generally, yes. Sparks mean uncontrolled current flowing in places it shouldn't. Often, sparks are generated when something has shorted out. Short circuits generate a lot of unwanted current and a lot of unwanted heat that can melt components of the circuit. So if you're seeing sparks, it's probably already too late and you've fried something.
The only other sparks you may encounter are across switch contacts, particularly with an inductive load such as a motor. Inductive loads will continue pushing current through a circuit, even after it has been opened. This back-current can generate a voltage large enough to overcome the breakdown voltage of air and create an arc. This damages switch contacts. Arcing powerful enough can melt the contacts and/or simply override the switch. So, arcing is generally a bad sign and should be avoided. This is often easily fixed in DC circuits by placing a reverse-biased diode across the inductor or inductive load. Power factor correction will fix this in an AC circuit.

If circuit is bad how can you find out?
If you have power to a circuit (you can tell with a multi meter), and it does not do what it is supposed to it is bad. Make sure the fuse is good. If fuses keep blowing then there is too much current, which is usually indicative of a short. If you see smoke, there's a good chance you're circuit is bad. An electronics book will tell you what to look for if you are trying to troubleshoot a circuit board. Many times the board will need to be replaced as individual components are too small and impossible to get at to change.
How will you know if the transistor is working or faulty?
Impossible to give a specific answer without more information. Is it a BJT or a FET? Most general answer is you first have to understand the circuit using the transistor and what it's supposed to do. Then, 1. Check that the power supply voltages are correct. 2. Check that the DC biases are correct. 3. Check that the input signal is correct. 4. Check the output. But you have to know in advance what to expect.
What is a good thing about series circuit?
There's not much good things about a series circuit, but here's one that i know about. A series circuit has more than one power source or output device. It uses a single path to connect all the devices. An advantage of a series circuit is that you can add more power devices, such as more batteries, and increase the force of the output. This will give you more power. P.S. If you wanna see a bad thing about a circuit, then just type, What is a bad thing about a series circuit? in that box thingy. PEACE ADAM K HAPPINESS
Can particle wood sub floor be repaired and can tile be put on this floor?
The best way to repair particle board sub-flooring is to cut out the bad spot and replace with new board. You can only use vinyl and self stick tile over particle board. Ceramic tile cannot because the moisture in the thin-sets will break down the particle board.
What must you do if a 25KW Power Distribution Panel circuit breaker trips and wont reset?
That means either there is a load (appliance or fixture) connected in the circuit that has a short and it needs disconnected before trying to reset. Or the breaker itself has gone bad and needs replaced.
How can you tell if you have a stuck relay or bad circuit board?
bad relayhow
What causes the air condition fan not to come on?
faulty thermostat, stuck fan relay, bad fan motor, no voltage to motor, bad circuit board, bad run capacitor...
What happpens when the anode and cathode touch?
A short circuit occurs. Depending on the potential sparks, fire and other bad things may happen.
What would cause a short periodic low hum to come from a circuit breaker?
A bad circuit breaker. Replace it.

Why does my LCD TV have no power all of a sudden?
Could Be a fuse on the Circuit Board or The Power Supply Capacitors are bad.
Will the lights on the dash come on if your computer board is bad?
yes they should.
What causes a distributor to send no sparks and if there other part that send sparks to a 1991 Honda accord?
Bad distributor Bad coil Bad distributor cap Bad rotor
How to fix Brake light circuit board Chevy 1500?
There was a couple years that Chevy and GMC used a circuit board in the tail light assembly. It was a bad design. We had several in our fleet at work and many went bad. They are available from the dealer new. Not much you can do to repair the old one, just replace it with a new one.
Who repairs integrated circuit boards?
One possibility is the manufacturer of that particular board. Many have repair/exchange programs. If the board itself is physically broken and/or burned, it is probably not repairable. If components on the board are bad, it may be repaired. One possibility is the manufacturer of that particular board. Many have repair/exchange programs.

Can bad spark plugs cause your car to lose power and backfire in the intake manifold?
having bad spark plugs could effect how the spark sparks and when it sparks. new plugs is never a bad idea
Why doesn't the alternator light come on when key is turned to on?
Could be a bad bulb Could be a bad voltage regulator (circuit not opening on engine shut down)
