An electric DC circuit is attached to a 12 volt battery and has a 3 ohm resistor in it find the current flowing through the circuit?
If the 3-ohm resistor is the ONLY thing in the circuit, then the current flowing through it is (12 volts)/(3 ohms) = 4 amperes. If there are other things in the circuit besides the resistor, then the current depends on all of them.
Enlist any four effects of electric current on conductor with one example of each?
Effects of an Electric current -1) Heating effect -e.g. - Heater / Geyser etc.2) Magnetic effect -e.g. - Electric Bell etc.3) Chemical effect -e.g. - Battery charging etc.4) Lighting effect -e.g. - Electric bulb etc.
An electric DC circuit is attached to a 12-volt battery and has a 3-ohm resistor in it find the current flowing through the circuit?
Use the equation, V= IR from Ohm's Law V is the voltage, I is the current, and R is the resistance in ohms So then, solve the equation for I (the current) and you get I=V/R. Then just plug in the values... I= 12/3, which equals 4 A. (For current, it is measured in amperes, or just "A" as the unit.)
Does electrey faster in thick wire or thin one?
The speed of an electric signal or current depends on the material, not on the thickness. In metal, it is usually about 2/3 the speed of light in a vacuum. On the other hand, a thin wire has a higher electrical resistance than a thick wire (other things being equal). But this does not affect the speed.
What are the three effects of electric current?
Death, injury, and electricutionIf we ignore the above, humourous(!), attempt at an answer, then the three effects of an electric current are (1) heating effect, (2) chemical effect, and (3) magnetic effect.Examples of the heating effect include electric heaters, kettles, stoves, etc. An examples of the chemical effect is electroplating. Examples of the magnetic effect includes relays, motors, etc.The SI unit of current, the ampere, is defined in terms of the force between two parallel conductors due to their magnetic fields (i.e. the magnetic effect).

What are 3 factors which affect the magnitude of magnetic force on current-carrying conductors?
Electric current, magnetic field intensity, length of the conductor, angle between the electric current and magnetic field
What are the 3 electric hobs?
The three (electric) things (hobs) that you put your pans on when cooking.
What is starting current for a 6.7kw 3 phase electric motor?
One need to know the voltage, the power factor and starting torque, to derive the starting current. The information provided in the question is not sufficient.

What are the 3 metallic properties?
They are lustrous and malleable They conduct heat They conduct electric current
What are the 3 properties of metal?
They are lustrous and malleable They conduct heat They conduct electric current
How many things are needed to have current?
3 things Volts, ohms, and amps
If electric heater works on 115 V and draws 3 A of current how much power does it use?
The formula you are looking for is W = I x E.
Can I put an electric shower on a timer switch?
Most timer swiches are designed to operate with loads of up to 13 amps or 3 kW. Electric showers use around 8 kW (30-35 amps), so you would need a high-current timer.
What are 3 examples of electrical energy?
. lightning . batteries . energy generated by electric eels
What are the two things needed to make current flow in electricity?
A flow of electrons is needed to have a current. And there (usually) must be a complete circuit. And you need a voltage to make the current move around your circuit. All tied up in Ohms Law - which I'll leave to you.
