If the current flowing trough a 10 ohm resistor is 15 mA the power consumed in the resistor is?
The power consumed in a resistor can be calculated using the formula ( P = I^2 R ), where ( P ) is power, ( I ) is current, and ( R ) is resistance. In this case, with a current of 15 mA (or 0.015 A) flowing through a 10 ohm resistor, the power consumed is ( P = (0.015)^2 \times 10 = 0.00225 \times 10 = 0.0225 ) watts or 22.5 mW.

How does work ohmmeter?
ANY METER needs some kind of current flow to operate. Internal in the meter there are batteries that provide current that when passed trough a resistor will develop voltage as a function of the current. the meter will read this current and display the resistor size to cause this current to flow.
How it is possible to make a constant current source?
ANSWER: one way tie a zener x volts from B+ to ground with a resistor. that gives you a reference voltage using an PNP tie the base to the reference voltage collector goes to the load and the emitter is tied to +B trough a resistor Since the emitter follows the base then the current should be +B volts -zener voltage - Vbe or .6 v. that is it.
Is the current pass through parallel short resistance?
no.because current always try to flow trough low resistance path.as short circuit has low resistance current pass trough short circuit
When an electric current flows trough a long conductor each free electron move?
An electric current flowing through a long conductor has electrons moving end to end, uniformly pushing one ahead of the other. The starting and stopping of flow of electrons from end to end is essentially instant.

Why would your blower fan resister stop working?
Because for each speed except the higgest one, to slow the motor of the fan, a resistor is choose and it's a big resistor, bigger to slow the speed and after long use or if the motor is defect (use to much currant), the resistor burn and no currant can pass trough
If an EMF of 1 volt causes a current of 1 ampere what is the resistance of the material through which the current is flowing?
1/1 = 1ohm MR. volta [italian] Determined that it would take 1 volt to pass 1 amp trough a 1 ohm resistor MR ampere [ french] Ditermined that it would take 1 ohm and 1 volt to pass one ampere MR ohms [english] determinaed that for 1 volt and one ampere the resistance must be 1 ohm. mr watts determined that the product of volts x ampere will equal one watt [power]

How is an ohmmeter connected to a circuit?
ANY METER needs some kind of current flow to operate. Internal in the meter there are batteries that provide current that when passed trough a resistor will develop voltage as a function of the current. the meter will read this current and display the resistor size to cause this current to flow.
How does a zener diode works?
A zener diode is designed to be operated in reverse bias, and have a specified breakdown voltage. For example, if you wanted a part that is supposed to get 10V applied to it, and you only have a 12V rail, you can put a resistor and a 10V zener diode in series, and the zener diode will make sure that only 10V get dropped across it. Any more and it will begin conducting. It will draw enough current to drop the excess voltage across the series resistor. If the load on the output terminals increases, tending to reduce the output voltage, the Zener just takes less current. The idea is that the total current through the series resistor is enough to stabilise the output at 10V. ANSWER: A zener is a diode that has the property that when reversed bias is applied to exibit a breakdown of a voltage with a sharp knee. This property can be used as a regulator since the voltage will not change it the current trough the zener changes.
