What else can I help you with?
What is voltage of a circuit with 15 amps of current andtoaster with 8ohms of resistance?
V=I*R Where: V is voltage I is the current in ampers R is resistance in ohms. So, if the current is 15 A and the resistance is 5 ohms, then the voltage must be 15 A *5 ohms = 75 V.
What is an example of a series circuit?
Series circuits, I'm doing my junior cert science so this may be wrong, but I'm pretty sure an example would be Christmas lights. If one blows they all are extinguished, because they share the one current of electricity. Car lights are parallel circuits.... I can't think of another series one, but I hope I helped a bit.
What you the current in an ac circuit with 120 volts and a 60 watt light bulb?
Questions seem to be two! First is the direct current in a circuit with 12 V battery and 3 ohm resistor in it. The answer is 4 ampere if there is negligible internal resistance in the battery. By ohm's law V = R I So, I = V/R Second one is the alternating current with 120V given to 60 W bulb. The answer is 0.5 ampere. This 0.5 is the rms value of alternating current. Power P = V I So, I = P/V
What is the purpose of the neutral conductor?
The purpose of neutral conductor is to carry the unbalanced load current. It is also a grounded conductor, which effectively places a limit on how much voltage could be present from hot to ground, a safety concern.
Lead acid batteries short circuit current?
You would have infinite amperes if there was no resistance in the battery plates, the battery terminal posts and in the wires that are shorting the battery.But there is always resistance in those things so - depending on the thickness and therefore the effective resistance of the wires that are shorting the battery - the short circuit current will be from a few amps to many hundreds of amps and, unless someone sees it and acts quickly to remove the cause of the short, that current will continue until the battery either explodes or just runs down very fast.I've seen them go both ways, along with the shorting wires smoking and then glowing like an electric fire, and also I have seen molten globs of hot metal dripping off from carelessly misplaced tools such as heavy screwdrivers, particularly if made of aluminum, and such things as small wrenches.
Light bulbs how does running electricity through the bulb create light?
The electricity runs through a coil of Tungsten. Tungsten has a very high resistance. As per Joule's Law, energy radiated is directly proportional to resistance. The energy radiated is so large that the coil starts to glow and light is produced.
Does the voltage that runs through different appliances vary according to the resistance of the appliances?
No, it is the current (amperes) that vary according to the resistance.
When the electric current runs through the wire loop of a motor it makes a?
Circuit
Jeep liberty Part time light stays on why?
There is a malfunction in the circuit that runs the light. Could be with the switch on the transfer case, in the wiring, or in the cluster.
When electricity runs through light bulb what other type of energy is produced?
When electricity runs through a light bulb, it produces light energy and some heat energy as well.
What is a branching circuit?
Each of the circuit breakers in the service panel controls electricity on a branch circuit. A branch circuit is typically a loop of wire that runs from the service panel, out to receptacles, light fixtures, appliances, etc. and back again.
When energy runs through a light bulb what kind of energy does the light bulb produce?
A light bulb uses electrical energy, and produces light, as well as heat.
What are the two kinds of blood circuit?
Veins and Arteries, I believe is what you are asking about. Arteries carry freshly oxygenated blood from the lungs; veins return the 'spent' blood to the lungs for a recharge. Arteries carry greater blood pressure. The two major blood circuit are the Pulmonary Circuit which is the circuit that runs through the lungs and the Systemic Circuit, Which is the circuit that takes the blood through the body.
How do 1 wire motorcycle turn signals work?
The wire that runs through to the light caries the power and the blinker itself has metal that touches the frame when it is screwed on and it grounds it to the frame. When it is grounded to the frame it completes the circuit. After it comes on there is a computer that senses it and makes it blink instead of just a steady light.
Is it safe to use a 20 amp circuit for lighting runs?
Yes : but in a residential case a 15 amp circuit would be better
Which appliances heat up when electicity runs through them?
Appliances such as toaster ovens, electric stoves, electric heaters, and hair dryers heat up when electricity runs through them due to the resistance in their heating elements. This resistance causes the electrical energy to be converted into heat energy, which is then used for cooking, heating, or drying purposes.
Why observed cell voltages are usually less than calculated E values?
Because in the real world, all cells have some internal resistance and when a current runs through that resistance, there is a voltage drop.
